ALTER AGGREGATE()		 SQL Commands		     ALTER AGGREGATE()

NAME
       ALTER AGGREGATE - change the definition of an aggregate function

SYNOPSIS
       ALTER AGGREGATE name ( type ) RENAME TO new_name
       ALTER AGGREGATE name ( type ) OWNER TO new_owner
       ALTER AGGREGATE name ( type ) SET SCHEMA new_schema

DESCRIPTION
       ALTER AGGREGATE changes the definition of an aggregate function.

       You  must own the aggregate function to use ALTER AGGREGATE.  To change
       the schema of an aggregate function, you must also have	CREATE	privi‐
       lege  on the new schema.	 To alter the owner, you must also be a direct
       or indirect member of the new owning role, and that role must have CRE‐
       ATE  privilege  on the aggregate function's schema. (These restrictions
       enforce that altering the owner doesn't do anything you couldn't do  by
       dropping	 and  recreating  the aggregate function. However, a superuser
       can alter ownership of any aggregate function anyway.)

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

       type   The  argument  data  type of the aggregate function, or * if the
	      function accepts any data type.

       new_name
	      The new name of the aggregate function.

       new_owner
	      The new owner of the aggregate function.

       new_schema
	      The new schema for the aggregate function.

EXAMPLES
       To rename the aggregate function myavg for type integer to my_average:

       ALTER AGGREGATE myavg(integer) RENAME TO my_average;

       To change the owner of the aggregate function myavg for type integer to
       joe:

       ALTER AGGREGATE myavg(integer) OWNER TO joe;

       To  move	 the  aggregate	 function  myavg  for type integer into schema
       myschema:

       ALTER AGGREGATE myavg(integer) SET SCHEMA myschema;

COMPATIBILITY
       There is no ALTER AGGREGATE statement in the SQL standard.
