Removes an aggregate function.
DROP AGGREGATE [IF EXISTS] name ( type [, ...] ) [CASCADE | RESTRICT]
DROP AGGREGATE will delete an existing aggregate function. To execute this command the current user must be the owner of the aggregate function.
- IF EXISTS
- Do not throw an error if the aggregate does not exist. A notice is issued in this case.
- The name (optionally schema-qualified) of an existing aggregate function.
- 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.
- Automatically drop objects that depend on the aggregate function.
- Refuse to drop the aggregate function if any objects depend on it. This is the default.
To remove the aggregate function myavg for type integer:
DROP AGGREGATE myavg(integer);
There is no DROP AGGREGATE statement in the SQL standard.
