NAME
       DROP AGGREGATE - remove a user-defined aggregate function

SYNOPSIS
       DROP AGGREGATE name ( type ) [ CASCADE | RESTRICT ]

   INPUTS
       name   The name (optionally schema-qualified) of an existing aggregate function.

       type   The  input  data type of the aggregate function, or * if the function accepts any input type.  (Refer to the PostgreSQL User's Guide
	      for further information about data types.)  [Comment: This should become a cross-reference rather than a hard-coded chapter number]

       CASCADE
	      Automatically drop objects that depend on the aggregate.

       RESTRICT
	      Refuse to drop the aggregate if there are any dependent objects.	This is the default.

   OUTPUTS
       DROP AGGREGATE
	      Message returned if the command is successful.

       ERROR: RemoveAggregate: aggregate 'name' for type type does not exist
	      This message occurs if the aggregate function specified does not exist in the database.

DESCRIPTION
       DROP AGGREGATE will delete an existing aggregate definition. To execute this command the current user must be the owner of the aggregate.

   NOTES
       Use CREATE AGGREGATE [create_aggregate(7)] to create aggregate functions.

USAGE
       To remove the myavg aggregate for type int4:

       DROP AGGREGATE myavg(int4);

COMPATIBILITY
   SQL92
       There is no DROP AGGREGATE statement in SQL92; the statement is a PostgreSQL language extension.
