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);
