Yeah, that's a point that needs careful thought. I don't think it
means that we shouldn't have something in core; after all, this is a
problem that is created in part by the way that PostgreSQL itself
works, and I think it would be quite unfriendly if we refused to do
anything about that in the core distribution. On the other hand, it
might be a good reason not to back-patch, which is something most
people don't seem enthusiastic about anyway.
