I believe so.

Not really. What's happening I believe is that it's looking at the final
state of the database and seeing that a row in test2 matches. It then
also needs to determine if a matching row was re-inserted into test1
which it doesn't currently do. Part of the reason for this was a mistake
in reading a piece of the spec that made it appear that such constructs
were illegal, so they weren't coded for.

I have a test patch that I think fixes the base constraint and the no
action referential actions against a 7.2 but it should probably apply
okay against 7.1.x. (I think I sent it to the list a while back,
if not you can write me).
