Whitespace of the same width as the most recent output of PROMPT1. Lists text search templates. If set to queries, psql prints each query to standard output as it is sent to the server. Lists functions, together with their result data types, argument data types, and function types, which are classified as “agg” (aggregate), “normal”, “procedure”, “trigger”, or “window”. Furthermore, psql provides facilities for ensuring that variable values used as SQL literals and identifiers are properly quoted. The colon syntaxes for array slices and type casts are PostgreSQL extensions, which can sometimes conflict with the standard usage. Shows the copyright and distribution terms of PostgreSQL. To retrieve the content of the variable, precede the name with a colon, for example: This works in both regular SQL commands and meta-commands; there is more detail in SQL Interpolation, below. While C-style block comments are passed to the server for processing and removal, SQL-standard comments are removed by psql. wrapped format is like aligned but wraps wide data values across lines to make the output fit in the target column width. Editing is done in the same way as for \edit. If pattern is specified, only those servers whose name matches the pattern are listed. Specifies the record (line) separator to use in unaligned output format. Lists event triggers. This is set every time you connect to a database (including program start-up), but can be changed or unset. See Variables below for details. If the form \dF+ is used, a full description of each configuration is shown, including the underlying text search parser and the dictionary list for each parser token type. The usual SQL case folding and quoting rules apply to column names. The \if and \elif commands read their argument(s) and evaluate them as a boolean expression. If psql detects a problematic console code page, it will warn you at startup. These variables can be set using the SET statement, by editing the postgresql.conf configuration file, through the PGOPTIONS environmental variable (when using libpq or a libpq-based application), or through command-line flags when starting the postgres server. Use separator as the record separator for unaligned output. Prompt 1 is the normal prompt that is issued when psql requests a new command. The port number at which the database server is listening. Lists aggregate functions, together with their return type and the data types they operate on. If colD is not specified, then there must be exactly three columns in the query result, and the column that is neither colV nor colH is taken to be colD. (Setting ECHO to all or queries is often advisable when using \gexec.) Sets the output format to one of aligned, asciidoc, csv, html, latex, latex-longtable, troff-ms, unaligned, or wrapped. Advanced users can use regular-expression notations such as character classes, for example [0-9] to match any digit. (This notation is comparable to Unix shell file name patterns.) This command fetches and edits the definition of the named function or procedure, in the form of a CREATE OR REPLACE FUNCTION or CREATE OR REPLACE PROCEDURE command. This is mainly useful for regression tests. If value is omitted the command toggles footer display on or off. After the editor exits, the updated command is executed immediately if you added a semicolon to it. The database session user name. Unofficial documentation for PostgreSQL hooks. Sets the target width for the wrapped format, and also the width limit for determining whether output is wide enough to require the pager or switch to the vertical display in expanded auto mode. If value is specified it must be either on or off which will enable or disable display of a locale-specific character to separate groups of digits to the left of the decimal marker. The prompts psql issues can be customized to your preference. The default is 0. (To select this behavior on program start-up, use the switch -E.) If you set this variable to the value noexec, the queries are just shown but are not actually sent to the server and executed. Whatever remains in the query buffer is redisplayed. Query logging, single-step mode, timing, and other query execution features apply to each generated query as well. Meta-commands are often called slash or backslash commands. (The expansion of this value might change during a database session as the result of the command SET SESSION AUTHORIZATION.). Run in single-step mode. Also, if an individual command cannot be executed inside a transaction block, specifying this option will cause the whole transaction to fail. Because carriage return and line feed characters cannot be safely quoted on all platforms, the :'variable_name' form prints an error message and does not substitute the variable value when such characters appear in the value. Before PostgreSQL 9.6, the -c option implied -X (--no-psqlrc); this is no longer the case. The modifiers t (tables) and i (indexes) can be appended to the command, filtering the kind of relations to list. (The latter form is almost always preferable, unless you are very sure of what is in the variable.) In addition, if columns is zero then the wrapped format only affects screen output. For example. PL/Python — Python Procedural Language, 55. Learn more about psql in our SQL cheat sheet and the official psql documentation. The default setting is ascii. Unique abbreviations are allowed. It describes all the functionality that the current version of PostgreSQL officially supports. :-- This is a standard SQL comment Alternatively, C-style block comments can be used: /* multiline comment * with nesting: /* … To learn more about managing PostgreSQL (but without the Ubuntu specifics) see the official PostgreSQL documentation. In general, the higher the number the more borders and lines the tables will have, but details depend on the particular format. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. (See Section 52.2.2.1 for more details about how the server handles multi-query strings.) If this variable is set to ignorespace, lines which begin with a space are not entered into the history list. For example: At the prompt, the user can type in SQL commands. DigitalOcean Community Tutorials. command must be either a command string that is completely parsable by the server (i.e., it contains no psql-specific features), or a single backslash command. Basic PostgreSQL client applications for Windows. Bug Reporting Guidelines I. Tutorial 1. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. This feature was shamelessly plagiarized from tcsh. The query is not actually executed; however, if it contains some type of syntax error, that error will be reported in the normal way. This might not be necessary in HTML, but in LaTeX you must have a complete document wrapper. Specifies whether to use color in diagnostic messages. This option can only be used in combination with one or more -c and/or -f options. If you want to use psql to connect to several servers of different major versions, it is recommended that you use the newest version of psql. If untrusted users have access to a database that has not adopted a secure schema usage pattern, begin your session by removing publicly-writable schemas from search_path. The output of command, similar to ordinary “back-tick” substitution. This is set every time you connect to a database (including program start-up), and when you change the encoding with \encoding, but it can be changed or unset. Specifies options to be placed within the HTML table tag. Sets the field separator to use in unaligned output format to a zero byte. This mode is provided for those who insist on it, but you are not necessarily encouraged to use it. The default is to print nothing, which can easily be mistaken for an empty string. If no value is given, the title is unset. Therefore, a construction such as ':foo' doesn't work to produce a quoted literal from a variable's value (and it would be unsafe if it did work, since it wouldn't correctly handle quotes embedded in the value). The optional topic parameter (defaulting to commands) selects which part of psql is explained: commands describes psql's backslash commands; options describes the command-line options that can be passed to psql; and variables shows help about psql configuration variables. This provides acc… If this option is used, none of this happens. Contents of this repository were compiled by Begishev Nikita and Goncharov Vladimir, neither of whom appear to be a developer or a maintainer of the PostgreSQL Database Management System. Lists default access privilege settings. These constructs deal correctly with quotes and other special characters embedded within the variable value. Sets the title of any tables being printed as the result of a query or unset any such title. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. Alternatively, input can be from a file or from command line arguments. Examples: The default is + on Unix systems (corresponding to the default editor vi, and useful for many other common editors); but there is no default on Windows systems. If for some reason you do not like the tab completion, you can turn it off by putting this in a file named .inputrc in your home directory: (This is not a psql but a Readline feature. Use \i for that.). For example, to set the output format to LaTeX, you could write -P format=latex. Lists access methods. It is probably not too useful in interactive mode. The default value is off. The ALTER ROLE and ALTER DATABASE commands are used to define per-role and per-database configuration settings. The meaning of the privilege display is explained in Section 5.7. If set to a value of ignoredups, lines matching the previous history line are not entered. Within an argument, text that is enclosed in backquotes (`) is taken as a command line that is passed to the shell. If this doesn't work out as expected, the client encoding can be overridden using the environment variable PGCLIENTENCODING. If pattern is specified, only those roles whose names match the pattern are listed. If filename is - (hyphen), then standard input is read until an EOF indication or \q meta-command. Toggles the display of output column name headings and row count footer. The error rollback mode works by issuing an implicit SAVEPOINT for you, just before each command that is in a transaction block, and then rolling back to the savepoint if the command fails. Meta-Commands. It is released under the Library General Public Licence, or LGPL.. Downloads are available in source and binary formats at the PostgreSQL downloads site To show the values of all variables, call \set without any argument. postgresql 90 official documentation volume ii server administration Sep 01, 2020 Posted By Edgar Wallace Library TEXT ID e68218b5 Online PDF Ebook Epub Library postgresql global development group fultus corporation 2011 paperback good disclaimera copy that has been read but remains in clean condition all pages are intact and PostgreSQL Coding Conventions 53. Whenever a command is executed, psql also polls for asynchronous notification events generated by LISTEN and NOTIFY. Thus it is fine to type \help alter table. is shown in the right-hand margin of the first line, and again in the left-hand margin of the following line. In between there may be any number of \elif clauses, which may optionally be followed by a single \else clause. To intersperse text output in between query results, use \qecho. If it is not unaligned, it is set to unaligned. Prompts can contain terminal control characters which, for example, change the color, background, or style of the prompt text, or change the title of the terminal window. matches any single character. $ is not needed as a regular-expression character since the pattern must match the whole name, unlike the usual interpretation of regular expressions (in other words, $ is automatically appended to your pattern). Do not use Readline for line editing and do not use the command history. If the form \dew+ is used, the access privileges, options, and description of the foreign-data wrapper are also shown. Backslash-semicolon is not a meta-command in the same way as the preceding commands; rather, it simply causes a semicolon to be added to the query buffer without any further processing. Cloud-native document database for building rich mobile, web, and IoT apps. The host name of the database server, truncated at the first dot, or [local] if the connection is over a Unix domain socket. If you prefer autocommit-off, you might wish to set it in the system-wide psqlrc file or your ~/.psqlrc file. In prompt 2 %R is replaced by a character that depends on why psql expects more input: - if the command simply wasn't terminated yet, but * if there is an unfinished /* ... */ comment, a single quote if there is an unfinished quoted string, a double quote if there is an unfinished quoted identifier, a dollar sign if there is an unfinished dollar-quoted string, or ( if there is an unmatched left parenthesis. It is also convenient to have a ~/.pgpass file to avoid regularly having to type in passwords. The location of the history file can be set explicitly via the HISTFILE psql variable or the PSQL_HISTORY environment variable. If value is omitted the command toggles between regular and tuples-only output. The command history is automatically saved when psql exits and is reloaded when psql starts up. PostgreSQL responds with the number of records inserted: INSERT 0 2 For more on INSERT, see INSERT in the PostgreSQL official docs. Keep in mind that when using this feature, a query might fail after having already displayed some rows. See \a, \C, \f, \H, \t, \T, and \x. For example, \dt foo*. To set a tab as field separator, type \pset fieldsep '\t'. If pattern is specified, only those mappings whose user names match the pattern are listed. Expressions that do not properly evaluate to true or false will generate a warning and be treated as false. For the sake of readability, it is recommended to always associate a human-readable comment with every object. If \d is used without a pattern argument, it is equivalent to \dtvmsE which will show a list of all visible tables, views, materialized views, sequences and foreign tables. The generated queries are sent literally to the server for processing, so they cannot be psql meta-commands nor contain psql variable references. Within a pattern, * matches any sequence of characters (including no characters) and ? Writes the current query buffer to the file filename or pipes it to the shell command command. The character with the indicated octal code is substituted. But within double quotes, * and ? 2. This command sets options affecting the output of query result tables. Setting up the JDBC Driver Getting the Driver Setting up the Class Path Preparing the Database Server for JDBC Creating a Database 3. Should you need to include an actual double quote character in a pattern, write it as a pair of double quotes within a double-quote sequence; again this is in accord with the rules for SQL quoted identifiers. PostgreSQL 8.4 Official Documentation has been written by the PostgreSQL developers and other volunteers in parallel to the development of the PostgreSQL software. See Variables below. If no view is specified, a blank CREATE VIEW template is presented for editing. To ensure maximum compatibility in the future, avoid using such variable names for your own purposes. Use \lo_list to find out the large object's OID. The colon-quote syntax for escaping a variable's value as an SQL literal or identifier is a psql extension. which is translated to ., and $ which is matched literally. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. If omitted, colV is taken as column 1 and colH as column 2. colH must differ from colV. Parsing for arguments stops at the end of the line, or when another unquoted backslash is found. role-pattern and database-pattern are used to select specific roles and databases to list, respectively. The default setting is 0. Variable references in skipped lines are not expanded, and backquote expansion is not performed either. If no function is specified, a blank CREATE FUNCTION template is presented for editing. Copyright © 1996–2020 The PostgreSQL Global Development Group. This could for example be cellpadding or bgcolor. *bar* displays all tables whose table name includes bar that are in schemas whose schema name starts with foo. If you want to see the lines on the screen as they are read you must set the variable ECHO to all. The value of the selected prompt variable is printed literally, except where a percent sign (%) is encountered. Since colons can legally appear in SQL commands, an apparent attempt at interpolation (that is, :name, :'name', or :"name") is not replaced unless the named variable is currently set. Lists partitioned relations. Shows the descriptions of objects of type constraint, operator class, operator family, rule, and trigger. When this variable is set to on, processing will instead stop immediately. This is purely a convenience measure. Each row is terminated by the system-dependent end-of-line character, which is typically a single newline (\n) for Unix-like systems or a carriage return and newline sequence (\r\n) for Microsoft Windows. Note that you cannot just connect to any database under any user name. The syntax for interpolating a value without any quoting is to prepend the variable name with a colon (:). Note that this is subtly different from the server function lo_export, which acts with the permissions of the user that the database server runs as and on the server's file system. (Note that the function body typically does not begin on the first line of the file.). See Section 33.1.2 for more information on all the available connection options. your experience with the particular feature or requires further clarification, The default is a comma. unicode style uses Unicode box-drawing characters. Lists operators with their operand and result types. The meaning of the privilege display is explained in Section 5.7. Type semicolon or \g to send it, or \r to cancel it by clearing the query buffer. Directory for storing temporary files. To include a single quote in an argument, write two single quotes within single-quoted text. However, backslash commands of the \d family should work with servers of versions back to 7.4, though not necessarily with servers newer than psql itself. If the current query buffer is empty, the most recently sent query is re-executed instead. If operator-family-pattern is specified, only functions of operator families whose names match that pattern are listed. If filename is specified, the file is edited; after the editor exits, the file's content is copied into the current query buffer. for ., (R+|) for R*, or (R|) for R?. You can specify any or all of these letters, in any order, to obtain a listing of objects of these types. If pattern is specified, only collations whose names match the pattern are listed. This is equivalent to setting the variable ECHO to all. PostgreSQL servers since version 12 do not support OID system columns anymore, thus LASTOID will always be 0 following INSERT when targeting such servers. If value is omitted the command toggles between regular and locale-specific numeric output. The :{?name} special syntax returns TRUE or FALSE depending on whether the variable exists or not, and is thus always substituted, unless the colon is backslash-escaped. (See Section 52.2.2.1 for more details about how the server handles multi-query strings.) If you call \set without a second argument, the variable is set to an empty-string value. Sets the border drawing style for the unicode line style to one of single or double. Defined substitutions are: The full host name (with domain name) of the database server, or [local] if the connection is over a Unix domain socket, or [local:/dir/name], if the Unix domain socket is not at the compiled in default location. Editor used by the \e, \ef, and \ev commands. This is equivalent to the command \o. If parentheses appear after \g, they surround a space-separated list of option=value formatting-option clauses, which are interpreted in the same way as \pset option value commands, but take effect only for the duration of this query. The asciidoc, html, latex, latex-longtable, and troff-ms formats put out tables that are intended to be included in documents using the respective mark-up language. If pattern is specified, only languages whose names match the pattern are listed. old-ascii style uses plain ASCII characters, using the formatting style used in PostgreSQL 8.4 and earlier. Lists type casts. Editing is done in the same way as for \edit. Also keep in mind that if you exit the session without committing, your work will be lost. Because of this, special parsing rules apply to the \copy meta-command. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. By convention, all specially treated variables' names consist of all upper-case ASCII letters (and possibly digits and underscores). These operations are not as efficient as the SQL COPY command with a file or program data source or destination, because all data must pass through the client/server connection. If command is not specified, then psql will list all the commands for which syntax help is available. Without argument, changes to the current user's home directory. This makes sure that the new password does not appear in cleartext in the command history, the server log, or elsewhere. When either -c or -f is specified, psql does not read commands from standard input; instead it terminates after processing all the -c and -f options in sequence. Using this option is subtly different from writing psql < filename. If command is an asterisk (*), then syntax help on all SQL commands is shown. So a valid value is any unambiguous case-insensitive match for one of: true, false, 1, 0, on, off, yes, no. results in sending the three SQL commands to the server in a single request, when the non-backslashed semicolon is reached. Default connection parameters (see Section 33.14). This is useful for creating output that might be intended to be read in by other programs, for example, tab-separated or comma-separated format. Native Language Support 54. The default is /tmp. The default is errors (meaning that context will be shown in error messages, but not in notice or warning messages). Lists schemas (namespaces). See Environment, below, for how to configure and customize your editor. Because of this, the server executes it as a single transaction even if the string contains multiple SQL commands, unless there are explicit BEGIN/COMMIT commands included in the string to divide it into multiple transactions. The arguments are separated from the command verb and each other by any number of whitespace characters. If the current table output format is unaligned, it is switched to aligned. When no dot appears, then the pattern matches only objects that are visible in the current schema search path. The ALTER DEFAULT PRIVILEGES command is used to set default access privileges. your experience with the particular feature or requires further clarification, If + is appended to the command name, database sizes, default tablespaces, and descriptions are also displayed. If the current query buffer is empty, the most recently sent query is described instead. SHOW name Parameters. Thus you can construct interesting references such as \set :foo 'something' and get “soft links” or “variable variables” of Perl or PHP fame, respectively. You must make sure that it makes sense where you put it. PostgreSQL 8.4 Official Documentation has been written by the PostgreSQL developers and other volunteers in parallel to the development of the PostgreSQL software. By default, only user-created languages are shown; supply the S modifier to include system objects. How To Connect to a Managed Database on Ubuntu 18.04. Turns on HTML query output format. Sets the string to be printed in place of a null value. From the official documentation: PostgreSQL Comments. psql provides variable substitution features similar to common Unix command shells. See \pset tableattr for details. aligned format is the standard, human-readable, nicely formatted text output; this is the default. If pattern is specified, only those roles whose names match the pattern are listed. View the manual. For foreign tables, the associated foreign server is shown as well. If access-method-pattern is specified, only functions of operator families associated with access methods whose names match that pattern are listed. The database server port to which you are currently connected. psql supports the Readline library for convenient line editing and retrieval. Specifies the field separator to be used in CSV output format. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. Whenever the pattern parameter is omitted completely, the \d commands display all objects that are visible in the current schema search path — this is equivalent to using * as the pattern. Before PostgreSQL 9.6, the -c option implied -X (--no-psqlrc); this is no longer the case. Each column of the row is stored into a separate variable, named the same as the column. Shows a list of all PostgreSQL large objects currently stored in the database, along with any comments provided for them. A number of these variables are treated specially by psql. Write all query output into file filename, in addition to the normal output destination. If \pset columns is zero, controls the width for the wrapped format and width for determining if wide output requires the pager or should be switched to the vertical format in expanded auto mode. If pattern is specified, only operators whose names match the pattern are listed. The completeness of the support for other systems depends on the availability and quality of client libraries. If + is appended to the command name, each access method is listed with its associated handler function and description. This is equivalent to the statement that the object can be referenced by name without explicit schema qualification.) Ordinary queries and other types of backslash commands may (and usually do) appear between the commands forming a conditional block. There is also a slight chance that using this option will reduce the start-up overhead. If the server requires password authentication and a password is not available from other sources such as a .pgpass file, the connection attempt will fail. If an unquoted colon (:) followed by a psql variable name appears within an argument, it is replaced by the variable's value, as described in SQL Interpolation below. SQL Syntax 5. Note that you probably don't want to specify border here, as that is already taken care of by \pset border. Unlike most other meta-commands, the entire remainder of the line is always taken to be the argument(s) of \sf, and neither variable interpolation nor backquote expansion are performed in the arguments.
