Re: freezing a particular field in a table

Perhaps a BEFORE UPDATE trigger, setting NEW.do_not_change_me =
OLD.do_not_change_me?

Is there a way where you can implement a situation in a postgres table
where a particular field cannot be changed when saved initially. I have
table and there's one particular integer field that should never be
changed in any record inserted... but I might need to allow the entire
record to be deleted... I was just wondering if there's a way to
implement something like this on a field (but not the entire row) at the
database level?
