       ALTER AGGREGATE - change the definition of an aggregate function


       ALTER AGGREGATE name ( type [ , ... ] ) RENAME TO new_name
       ALTER AGGREGATE name ( type [ , ... ] ) OWNER TO new_owner
       ALTER AGGREGATE name ( type [ , ... ] ) SET SCHEMA new_schema


       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 privilege 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


       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.

              The new name of the aggregate function.

              The new owner of the aggregate function.

              The new schema for the aggregate function.


       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;


       There is no ALTER AGGREGATE statement in the SQL standard.
