This option only affects the aligned and wrapped output formats. Lists foreign-data wrappers (mnemonic: “external wrappers”). The name of the database you are currently connected to. Copy all SQL commands sent to the server to standard output as well. 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. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. Lists tables, views and sequences with their associated access privileges. For example, to set the output format to LaTeX, you could write -P format=latex. Zero (the default) causes the target width to be controlled by the environment variable COLUMNS, or the detected screen width if COLUMNS is not set. If + is appended to the command name, each object is listed with its associated description. Informix (An object is said to be visible if its containing schema is in the search path and no object of the same kind and name appears earlier in the search path. Although you can use any output format with this feature, the default aligned format tends to look bad because each group of FETCH_COUNT rows will be formatted separately, leading to varying column widths across the row groups. Next How to Remove a Default Value From a Column. If this option is used, none of this happens. The colon-quote syntax for escaping a variable's value as an SQL literal or identifier is a psql extension. However, psql will waste a connection attempt finding out that the server wants a password. If the form \dFp+ is used, a full description of each parser is shown, including the underlying functions and the list of recognized token types. Tab-completion is also supported, although the completion logic makes no claim to be an SQL parser. 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 large amounts of data the SQL command might be preferable. If no filename is given, the current query buffer is copied to a temporary file which is then edited in the same fashion. The previous example would be more safely written this way: Variable interpolation will not be performed within quoted SQL literals and identifiers. If the current query buffer is empty, the most recently executed query is printed instead. All options other than the data source/destination are as specified for COPY. How to Add a Default Value to a Column in PostgreSQL-- Example: Orders have a default total of 0 cents alter table orders alter column total_cents set default 0; -- Example: Items are available by default alter table items alter column available set default true; Spread the word. 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. One example use of this mechanism is to copy the contents of a file into a table column. The default is 0. This is equivalent to \pset recordsep. Valid variable names can contain letters, digits, and underscores. This can be used to give your output descriptive tags. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. If this doesn't work out as expected, the client encoding can be overridden using the environment variable PGCLIENTENCODING. 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). Sybase ADS to SQL Server 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. If set to 1 or less, sending an EOF character (usually Control+D) to an interactive session of psql will terminate the application. The default is platform-dependent.
