NAME

       DROP_AGGREGATE - remove an aggregate function

SYNOPSIS

       DROP AGGREGATE [ IF EXISTS ] name ( argtype [ , ... ] ) [ 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.

       argtype
           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.
