I was on linux, although I just installed 8.0b2 dev 3 to my windows box
and tried #2 and still got a success.
Are you sure that the constraint wasn't deferred and/or that you weren't
doing this inside a function? In the former case there's a reading of spec
question for the timing of the actions (are they on the statement or at
check time -- we've done the latter although a rereading implies that we
may have previously read it wrong) and the latter, up until Tom's very
recent patch, any AFTER triggers (or foreign keys) waited until the end of
the original statement from the user to run.
