RESET

restore the value of a run-time parameter to the default value

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 [???](#sql-set) 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 [???](#runtime-config) 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 [???](#runtime-config) and on the [???](#sql-set)
    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
=============
