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

           RESET timezone;
