Well, I guess I'll change the requirements for the time being.
Thanks for catching this. I don't have a copy of 10.1 (I'm not apart
of Apple's Developer network).
Unfortunately, I can't offer any advise on trying to get PostgreSQL
to work with 10.1. I think you are correct that the PG community
is a more effective place to inquire (although there are several
people here that know there way around PG). I've heard good
things about the PG Hackers mailing list.
