NAME

       SHOW - show the value of a run-time parameter

SYNOPSIS

       SHOW name

       SHOW ALL

   INPUTS
       name   The name of a run-time parameter. See SET [set(7)] for a list.

       ALL    Show all current session parameters.

DESCRIPTION

       SHOW  will  display  the  current setting of a run-time parameter. These variables can be set using the SET statement, by editing the post-
       gresql.conf, through the PGOPTIONS environmental variable, or through a command-line flag when starting the postmaster.

       Even with autocommit set to off, SHOW does not start a new transaction block. See the autocommit section of the Administrator's	Guide  for
       details.

DIAGNOSTICS

       ERROR: Option 'name'
	      Message returned if name does not stand for an existing parameter.

EXAMPLES

       Show the current DateStyle setting:

       SHOW DateStyle;
		      DateStyle
       ---------------------------------------
	ISO with US (NonEuropean) conventions
       (1 row)

       Show the current genetic optimizer (geqo) setting:

       SHOW GEQO;
	geqo
       ------
	on
       (1 row)

       Show all settings:

       SHOW ALL;
		    name	      | 	       setting
       -------------------------------+---------------------------------------
	australian_timezones	      | off
	authentication_timeout	      | 60
	checkpoint_segments	      | 3
	   .
	   .
	   .
	wal_debug		      | 0
	wal_sync_method 	      | fdatasync
       (94 rows)

COMPATIBILITY

       The SHOW command is a PostgreSQL extension.

NAME

       RESET - restore the value of a run-time parameter to the default value

SYNOPSIS

       RESET configuration_parameter
       RESET ALL

DESCRIPTION

       RESET restores run-time parameters to their default values.  RESET is an alternative spelling for

	   SET configuration_parameter TO DEFAULT

       Refer to SET(7) for details.

       The default value is defined as the value that the parameter would have had, if no SET had ever been issued for it in the current session.
       The actual source of this value might be a compiled-in default, the configuration file, command-line options, or per-database or per-user
       default settings. This is subtly different from defining it as "the value that the parameter had at session start", because if the value
       came from the configuration file, it will be reset to whatever is specified by the configuration file now. See Chapter 18, Server
       Configuration, in the documentation for details.

       The transactional behavior of RESET is the same as SET: its effects will be undone by transaction rollback.

PARAMETERS

       configuration_parameter
	   Name of a settable run-time parameter. Available parameters are documented in Chapter 18, Server Configuration, in the documentation
	   and on the SET(7) reference page.

       ALL
	   Resets all settable run-time parameters to default values.

EXAMPLES

       Set the timezone configuration variable to its default value:

	   RESET timezone;

COMPATIBILITY

       RESET is a PostgreSQL extension.
