Hello. This is what returns the 2 servers:

Craig: Sorry about the details.

This is what we got:

Production server:
FreeBSD 8.2
Postgresql 9.1.2
Python 2.7.3 (default, Jul 10 2012, 21:36:33)

Interesting that your production server has the oldest FreeBSD and the newest Python. I'm still suspecting a library mismatch of some kind.

Is there anything vaguely informative in PostgreSQL's log files after the error? I'm hoping for a message from Python about a dlopen() or dlsym() error, or for a message from the dynamic linker.

If you redirect the postmaster's stderr to a file, it's possible dynamic linker messages might appear there but not be captured by Pg for logging. I don't see how you'd redirect that without stopping and starting the server, which you don't want to do.
