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.

       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.

	      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.
