This begs the question of if this is something PG should just allow
rather than denying the update.  Can you clarify exactly what hibernate
does?  Does it do:

#1: update x set col1 = col1 where pk = 'a';

Or does it do:

#2: update x set col1 = 'abc' where pk = 'a';

(where 'abc' happens to be the value of col1 in the database for
pk = 'a')?

It might be possible to ignore/optimize/whatever #1, perhaps, but
there's really nothing we could do about #2.  If it's #1, do other
databases which support column-level privs ignore those, or do they deny
the update like PG does today?

    Thanks,
