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. This is equivalent to \pset recordsep. The auto setting is only effective in the aligned and wrapped formats. For example, \dt int* displays tables whose names begin with int.

Lists foreign tables (mnemonic: external tables). Within the text enclosed in backquotes, no special quoting or other processing occurs, except that appearances of :variable_name where variable_name is a psql variable name are replaced by the variable's value. If set to 1 or less, sending an EOF character (usually Control+D) to an interactive session of psql will terminate the application. If it is not unaligned, it is set to unaligned.

This command fetches and shows the definition of the named view, in the form of a CREATE OR REPLACE VIEW command. This mode is provided for those who insist on it, but you are not necessarily encouraged to use it. The previous example would be more safely written this way: Variable interpolation will not be performed within quoted SQL literals and identifiers. In most other formats only values 0 (no border), 1 (internal dividing lines), and 2 (table frame) make sense, and values above 2 will be treated the same as border = 2.

Wow.. indeed by pressing the keys CONTROL + C, to cancel then execute the command again. Any possible solutions? If value is omitted the command toggles between regular and tuples-only output. In latex-longtable format, this controls the proportional width of each column containing a left-aligned data type. Sets the record separator to use in unaligned output format to a zero byte. (The latter form is almost always preferable, unless you are very sure of what is in the variable.) Turn on the expanded table formatting mode. The pager option can also be set to always, which causes the pager to be used for all terminal output regardless of whether it fits on the screen. Switches to unaligned output mode.
