RESET
Restores the value of a run-time system configuration parameter to the default value.
Synopsis
RESET <configuration_parameter>
RESET ALL
Description
RESET restores system configuration parameters to their default values. RESET is an equivalent command for
SET <configuration_parameter> TO DEFAULT
Refer to SET for details.
The default value is defined as the value that the parameter would have had, had no SET ever been issued for it in the current session. The actual source of this value might be a compiled-in default, the coordinator postgresql.conf 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 Server Configuration Parameters for more information.
The transactional behavior of RESET is the same as SET: its effects will be undone by transaction rollback.
Parameters
configuration_parameter
The name of a settable run-time system configuration parameter. See Server Configuration Parameters for details.
ALL
Resets all settable run-time configuration parameters to their default values.
