I actually started with the source: postgresql-8.3.5.tar.gz, from the source download location. I just build straight from that source... no mucking around with any of the sources.
I'm using a build that came from the postgres website, and just uses
the config that comes with it.
Hmm, you mean the EDB one-click installer? I don't offhand see another binary distro for OSX there.
It seems unlikely that the EDB build would be that broken on its own terms, but maybe you've run into some incompatibility between different releases of their build, or maybe you're trying to use their build against a database that was initdb'd with some other build. Have you upgraded Postgres since you ran initdb? If so, which version exactly did you initdb with?
