RESET(7)                                                  SQL Commands                                                  RESET(7)



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 [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 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 in the documentation and on the SET
              [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.
