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 defin-
       ing it as ''the value that the parameter had at session start'', because if the value came from the  configura-
       tion  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.
