RESET

Restores the value of a system configuration parameter to the default value.

Synopsis

  1. RESET <configuration_parameter>
  3. RESET ALL

Description

RESET restores system configuration parameters to their default values. RESET is an alternative spelling for SET configuration_parameter TO DEFAULT.

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 master hawq-site.xml configuration file, command-line options, or per-database or per-user default settings.

See Server Configuration Parameter Reference for more information.
