Save my name, email, and website in this browser for the next time I comment. When a query is executed repeatedly with the \watch command, a pager is not used by default. If omitted, colV is taken as column 1 and colH as column 2. colH must differ from colV. 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. The display is in milliseconds; intervals longer than 1 second are also shown in minutes:seconds format, with hours and days fields added if needed.

When the border setting is greater than zero, the linestyle option also determines the characters with which the border lines are drawn. If pattern is specified, only those extensions whose names match the pattern are listed. Unlike most other meta-commands, the entire remainder of the line is always taken to be the arguments of \copy, and neither variable interpolation nor backquote expansion are performed in the arguments. Asking for help, clarification, or responding to other answers. In HTML format, this specifies attributes to be placed inside the table tag. How do I fit an e-hub motor axle that is too big? Echo the actual queries generated by \d and other backslash commands. you never have to quote columns names (identifiers) and you never should quote them where it isn't required.

How can I change a PostgreSQL user password? If you call \set without a second argument, the variable is set to an empty-string value. Lists tables, views and sequences with their associated access privileges. If the environment variable PSQL_PAGER or PAGER is set, the output is piped to the specified program. If you want to know the Postgres (server) version, use select version (); if you want to know the version of the psql program, use psql -V from cmd.exe Both the system-wide startup file and the user's personal startup file can be made psql-version-specific by appending a dash and the PostgreSQL major or minor release identifier to the file name, for example ~/.psqlrc-15 or ~/.psqlrc-15.2. With arguments, \g provides a one-shot alternative to the \o command, and additionally allows one-shot adjustments of the output formatting options normally set by \pset.

Also, the regular expression special characters are matched literally in operator name patterns (i.e., the argument of \do). 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.

Execution of each query is subject to ECHO processing. Besides what @a_horse_with_no_name says your escaping is causing the problem. If pattern is specified, only languages whose names match the pattern are listed. Most variables that control psql's behavior cannot be unset; instead, an \unset command is interpreted as setting them to their default values. Normally, psql will dispatch an SQL command to the server as soon as it reaches the command-ending semicolon, even if more input remains on the current line. Without an argument, this command shows the current encoding. OTOH, using keywords as object names is rarely a good idea. If no value is given, the table attributes are unset. If + is appended to the command name, each parameter is listed with its data type, context in which the parameter can be set, and access privileges (if non-default access privileges have been granted).

Connect and share knowledge within a single location that is structured and easy to search. This was the code and error. Or, if the current query buffer is empty, the most recently executed query is copied to a temporary file and edited in the same fashion. Plain ASCII characters work everywhere, but Unicode characters look nicer on displays that recognize them. Sets the field separator for unaligned query output. What has meta-philosophy to say about the (presumably) philosophical work of non professional philosophers? The database server host you are currently connected to. is interpreted as a database name followed by a schema name pattern. When executing in interactive mode, the two commands behave identically. As in SQL names, placing double quotes around a pattern stops folding to lower case. When the last argument begins with |, the entire remainder of the line is taken to be the command to execute, and neither variable interpolation nor backquote expansion are performed in it. Use separator as the field separator for unaligned output. The current client character set encoding. Some commands take an SQL identifier (such as a table name) as argument. If you are already "inside" the psql prompt, you can only run SQL commands. A key feature of psql variables is that you can substitute (interpolate) them into regular SQL statements, as well as the arguments of meta-commands. Unique abbreviations are allowed. 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. Trying to start psql from within psql obviously doesn't work. In some cases it is worth typing -W to avoid the extra connection attempt. They can be changed or unset. In this list, spaces are not allowed around = signs, but are required between option clauses. So what *is* the Latin word for chocolate?

It is particularly useful when you need to copy-and-paste text that contains TAB characters. These settings can be role-specific, database-specific, or both. The default is the vertical bar (|). sortcolH identifies an optional sort column for the horizontal header. Use of the pager can be disabled by setting PSQL_PAGER or PAGER to an empty string, or by adjusting the pager-related options of the \pset command. If none of them is set, the default is to use more on most platforms, but less on Cygwin. Specifies the field separator to be used in CSV output format. If any of the commands fails and the variable ON_ERROR_STOP was set, a ROLLBACK command is sent instead. true if the last SQL query failed, false if it succeeded. Anything contained in single quotes is furthermore subject to C-like substitutions for \n (new line), \t (tab), \b (backspace), \r (carriage return), \f (form feed), \digits (octal), and \xdigits (hexadecimal). Note that psql will not attempt to wrap column header titles; therefore, wrapped format behaves the same as aligned if the total width needed for column headers exceeds the target. Lists partitioned relations. The other output formats work better. is shown in the right-hand margin of the first line, and again in the left-hand margin of the following line. This command is identical to \echo except that the output will be written to psql's standard error channel, rather than standard output. These version suffixes are added after determining the file path as explained above. Duress at instant speed in response to Counterspell. The user's personal startup file is named .psqlrc and is sought in the invoking user's home directory. To understand this issue, you need to know that SQL distinguishes between reserved and non-reserved key word tokens. In this group of commands, the letters E, i, m, s, t, and v stand for foreign table, index, materialized view, sequence, table, and view, respectively. 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. If value is specified it must be either on or off which will enable or disable tuples-only mode. This is equivalent to setting the variable QUIET to on. Alternative location for the command history file. If the form \des+ is used, a full description of each server is shown, including the server's access privileges, type, version, options, and description. If an argument is found that does not belong to any option it will be interpreted as the database name (or the user name, if the database name is already given). To show the values of all variables, call \set without any argument. The -n (--no-readline) command line option can also be useful to disable use of Readline for a single run of psql. If the current table output format is unaligned, it is switched to aligned. The number of distinct words in a sentence. However, the field separator character is not treated specially if it appears in a column's value; so CSV format may be better suited for such purposes. In a script file, only execution of that script is terminated. PTIJ Should we be afraid of Artificial Intelligence? If + is appended to the command name, each language is listed with its call handler, validator, access privileges, and whether it is a system object. Editing is done in the same way as for \edit. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? Valid variable names can contain letters, digits, and underscores. $ 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). Whatever remains in the query buffer is redisplayed. Making statements based on opinion; back them up with references or personal experience. syntax error at or near "-" in PostgreSQL, The open-source game engine youve been waiting for: Godot (Ep. If + is appended to the command name, each large object is listed with its associated permissions, if any. POSTMANPOSTMAN If it is not unaligned, it is set to unaligned. Lists data types. How can the mass of an unstable composite particle become complex? (The latter form is almost always preferable, unless you are very sure of what is in the variable.) To ensure maximum compatibility in the future, avoid using such variable names for your own purposes. If you see anything in the documentation that is not correct, does not match If a filename or |command argument is given, the query's output is written to the named file or piped to the given shell command, instead of displaying it as usual. If pattern is specified, only domains whose names match the pattern are shown. Not the answer you're looking for? This option can be repeated and combined in any order with the -c option. Thus it is fine to type \help alter table. These specify what the prompts psql issues should look like. The value of the selected prompt variable is printed literally, except where a percent sign (%) is encountered. The database server port to which you are currently connected. Gives syntax help on the specified SQL command. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If filename is - (hyphen), then standard input is read until an EOF indication or \q meta-command. That may or may not terminate the script; if it does not, all database-accessing commands will fail until another \connect command is successfully executed. This is equivalent to \pset recordsep. The expression argument of an \if or \elif command is subject to variable interpolation and backquote expansion, just like any other backslash command argument. What's wrong with my argument? If no filename is given, the current query buffer is copied to a temporary file which is then edited in the same fashion. This is equivalent to \pset fieldsep_zero. By default, only user-created roles are shown; supply the S modifier to include system roles. Print all nonempty input lines to standard output as they are read. Lists schemas (namespaces). Lists tablespaces. Treating the buffer as a single line primarily affects meta-commands: whatever is in the buffer after a meta-command will be taken as argument(s) to the meta-command, even if it spans multiple lines. (See also \errverbose, for use when you want a verbose version of the error you just got.). Sets the psql variable name to value, or if more than one value is given, to the concatenation of all of them. Without a pattern, only parameters that are set to non-default values are listed. When this variable is set to on and a backslash command queries the database, the query is first shown. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. (The expansion of this value might change during a database session as the result of the command SET SESSION AUTHORIZATION.). Before PostgreSQL 9.6, the -c option implied -X (--no-psqlrc); this is no longer the case. The previous example would be more safely written this way: Variable interpolation will not be performed within quoted SQL literals and identifiers. ), psql will return an error and terminate. Another way to obtain the same result as \copy to is to use the SQL COPY TO STDOUT command and terminate it with \g filename or \g |program. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? psql does not support embedded NUL bytes in variable values.). By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. 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. See \pset for a more general solution. See Variables below for details. If the modifier n (nested) is used, or a pattern is specified, then non-root partitioned relations are included, and a column is shown displaying the parent of each partitioned relation. If pattern is specified, only casts whose source or target types match the pattern are listed. Learn more about Stack Overflow the company, and our products.
