## 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)](https://www.chedong.com/phpMan.php/man/SET/7/markdown) 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 20 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 20
           and on the [**SET**(7)](https://www.chedong.com/phpMan.php/man/SET/7/markdown) 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.
