In the referenced discussion (10 years ago), Tom seemed OK with it and
Peter did not seem to like it much.

I think I agree with Peter here that it's not a very good idea, and I
don't see a big upside. With tablespaces it seems to make a little bit
more sense, but I'd still lean away from that idea.
