. Before PostgreSQL 8.4, psql allowed the first argument of a single-letter backslash command to start directly after the command, without intervening whitespace. The rest of the line is simply passed literally to the shell. When expanded mode is enabled, query results are displayed in two columns, with the column name on the left and the data on the right. Table Access Method Interface Definition, 61. Queries 8. For the sake of readability, it is recommended to always associate a human-readable comment with every object. \set without any arguments displays the names and values of all currently-set psql variables. Optionally, it associates the given comment with the object. Type semicolon or \g to send it, or \r to cancel it by clearing the query buffer. If there is no such row, the cell is empty. For example: This way you can also use LDAP for connection parameter lookup as described in Section 33.17. Sets the border drawing style for the unicode line style to one of single or double. Shows help information. Example: This command fetches and shows the definition of the named function or procedure, in the form of a CREATE OR REPLACE FUNCTION or CREATE OR REPLACE PROCEDURE command. An \unset command is allowed but is interpreted as setting the variable to its default value. Use \i for that.). The switch to select this behavior is -e. If set to errors, then only failed queries are displayed on standard error output. The colon syntaxes for array slices and type casts are PostgreSQL extensions, which can sometimes conflict with the standard usage.

See Environment, below, for how to configure and customize your editor. For each relation (table, view, materialized view, index, sequence, or foreign table) or composite type matching the pattern, show all columns, their types, the tablespace (if not the default) and any special attributes such as NOT NULL or defaults. This command is kept for backwards compatibility. Shows the descriptions of objects of type constraint, operator class, operator family, rule, and trigger. Cloud-native document database for building rich mobile, web, and IoT apps. This command is not available if psql was built without Readline support. The rest of the line is simply passed literally to the shell. 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 Unique abbreviations are allowed. Setting this variable to on is equivalent to the command line option -q. Note that only collations usable with the current database's encoding are shown, so the results may vary in different databases of the same installation. If set to none (the default), all lines read in interactive mode are saved on the history list. (That would mean one letter is enough.) Unlike \copy, this method allows the command to span multiple lines; also, variable interpolation and backquote expansion can be used. wrapped format is like aligned but wraps wide data values across lines to make the output fit in the target column width. Any complete queries are immediately executed; that is, if the query buffer contains or ends with a semicolon, everything up to that point is executed and removed from the query buffer. The target function can be specified by name alone, or by name and arguments, for example foo(integer, text). name: SERVER_VERSION: Shows the server’s version number. See Section 33.15 for more information. For example, \dt "FOO""BAR" will display the table named FOO"BAR (not foo"bar). 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. For foreign tables, the associated foreign server is shown as well. Connect to the database as the user username instead of the default. The meaning of the privilege display is explained in Section 5.7. Expressions that do not properly evaluate to true or false will generate a warning and be treated as false. Directory for storing temporary files. Before PostgreSQL 9.6, the -c option implied -X (--no-psqlrc); this is no longer the case. If the expression yields true then processing continues normally; otherwise, lines are skipped until a matching \elif, \else, or \endif is reached. This output is compatible with the CSV format of the server's COPY command. Again, the execution privileges are those of the local user, not the server, and no SQL superuser privileges are required. If the session user is a database superuser, then a #, otherwise a >. Before PostgreSQL 8.4, psql allowed the first argument of a single-letter backslash command to start directly after the command, without intervening whitespace.
