NAME

       ALTER TYPE - change the definition of a type


SYNOPSIS

       ALTER TYPE name OWNER TO new_owner
       ALTER TYPE name SET SCHEMA new_schema


DESCRIPTION

       ALTER  TYPE  changes the definition of an existing type.  The only cur-
       rently available capabilities are changing the owner and  schema  of  a
       type.

       You  must  own  the  type to use ALTER TYPE.  To change the schema of a
       type, 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 own-
       ing role, and that role  must  have  CREATE  privilege  on  the  type's
       schema.  (These restrictions enforce that altering the owner doesn't do
       anything you couldn't do by dropping and recreating the type.  However,
       a superuser can alter ownership of any type anyway.)


PARAMETERS

       name   The  name  (possibly  schema-qualified)  of  an existing type to
              alter.

       new_owner
              The user name of the new owner of the type.

       new_schema
              The new schema for the type.


EXAMPLES

       To change the owner of the user-defined type email to joe:

       ALTER TYPE email OWNER TO joe;

       To change the schema of the user-defined type email to customers:

       ALTER TYPE email SET SCHEMA customers;


COMPATIBILITY

       There is no ALTER TYPE statement in the SQL standard.
