   <para>
    No checks are made if functions or trigger procedures registered
    in this language still exist. To re-enable them without having
    to drop and recreate all the functions, the pg_proc's prolang
    attribute of the functions must be adjusted to the new object
    ID of the recreated pg_language entry for the PL.
