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.
