RESET

Description

Restores GUC 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.

Syntax

RESET {configuration_parameter | CURRENT_SCHEMA | TIME ZONE | TRANSACTION ISOLATION LEVEL | SESSION AUTHORIZATION | ALL };

Parameters

  • configuration_parameter

    Specifies the name of a settable GUC parameter.

    Value range: GUC parameters. You can view them by running the SHOW ALL statement.

    Some parameters that viewed by SHOW ALL cannot be set by SET. For example, max_datanodes.

  • CURRENT_SCHEMA

    Specifies the current schema.

  • TIME ZONE

    Specifies the time zone.

  • TRANSACTION ISOLATION LEVEL

    Specifies the transaction isolation level.

  • SESSION AUTHORIZATION
