Log message:
    Partial code review for ALTER DOMAIN patch.  Incorporates Rod Taylor's
    patches of 9-Dec (permissions fix) and 13-Dec (performance) as well as
    a partial fix for locking issues: concurrent DROP COLUMN should not
    create trouble anymore.  But concurrent DROP TABLE is still a risk, and
    there is no protection at all against creating a column of a domain while
    we are altering the domain.
