DROP AGGREGATE

Name

DROP AGGREGATE -- remove an aggregate function

Synopsis

DROP AGGREGATE [ IF EXISTS ] name ( type [ , ... ] ) [ CASCADE | RESTRICT ]

Description

DROP AGGREGATE removes an existing aggregate function. To execute this command the current user must be the owner of the aggregate function.

Parameters

IF EXISTS: Do not throw an error if the aggregate does not exist. A notice is issued in this case.
name: The name (optionally schema-qualified) of an existing aggregate function.
type: An input data type on which the aggregate function operates. To reference a zero-argument aggregate function, write * in place of the list of input data types.
CASCADE: Automatically drop objects that depend on the aggregate function.
RESTRICT: Refuse to drop the aggregate function if any objects depend on it. This is the default.

Examples

To remove the aggregate function myavg for type integer:

DROP AGGREGATE myavg(integer);

Compatibility

There is no DROP AGGREGATE statement in the SQL standard.
