RESET

Function

RESET restores run-time parameters to their default values. The default values are parameter default values complied in the postgresql.conf configuration file.

RESET is an alternative spelling for:

SET configuration_parameter TO DEFAULT

Precautions

RESET and SET have the same transaction behavior. Their impact will be rolled back.
