Обсуждение: Deferred Referential Constraint: Changing Referenced Key

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi there,

I was wondering if it is a bug or a feature. When I change a key on a
referenced table, and there is a foreign key deferred constraint, it
triggers imediately, not at the end of transaction.

If I change the reference first, it works as expected. Someone had the
same problem:

Where do I get if this problem has a solution or it has been seen?

The example in that message works for me in recent versions. You're going
to need to give a version and standalone example before we're going to be
able to help you.
