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 ??? 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 ??? 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 ??? and on the ??? reference page.

ALL
Resets all settable run-time parameters to default values.

Examples#

Set the timezone configuration variable to its default value:
