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.
