Hmm, that is a good point. It would be cleaner to throw a "can't
serialize" failure than have the RI triggers run under a different
snapshot. I am not sure if we can implement that behavior easily,
though. Can you think of a way to detect whether there's an RI conflict
against a later-started transaction?
