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



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 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 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.
