ALTER AGGREGATE(7)               SQL Commands               ALTER AGGREGATE(7)

       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  recre-
       ating the aggregate function. However, a superuser can alter ownership of any aggregate function anyway.)

       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.

       CREATE AGGREGATE [create_aggregate(7)], DROP AGGREGATE [drop_aggregate(7)]
