Re: deferred foreign keys

One more question: does the FK checker know to skip checking a
constraint if the column in question did not change during an update?

That is, if I have a user table that references an owner_id in an
owners table as a foreign key, but I update fields other than owner_id
in the user table, will it still try to verify that owner_id is a
valid value even though it did not change?

I'm using PG 7.4.

Thanks.
