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.
