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 priv-
       ilege 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
       CREATE  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   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.

       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.
