You could do this--create ON UPDATE and ON DELETE triggers that look
for distinguishing features of the default records (primary key value
or whatever) and RAISE ERROR if they match. They'll be executed for
every UPDATE and DELETE on the table, which may or may not be a
performance issue for you...
