Forum OpenACS Q&A: bboard administration kills PostgreSQL in OpenACS 3.2.5

I recently installed the RPMs for OpenACS 3.2.5.  I've used ACS and
OpenACS in the past, but I decided to take the RPMs for a spin with
PostgreSQL 7.1.

Everything on the site appears to work just fine, except for the
bboard administration.  I go to the bboard admin page
(http://localhost:8000/admin/bboard/add-new-topic.tcl) and enter a new
topic ("New test topic"), enter my last name ("Lerner"), indicate that
I want Q&A style forums, that the forum should be unmoderated, and
that I do not want to get notifications.  I choose the single matching
user from the list (i.e., myself), and then AOLserver dies on me!

Moreover, AOLserver claims that PostgreSQL isn't responding.  But this
isn't true; PostgreSQL happily continues to exist.

My AOLserver error log is below, and I hope that someone can identify
the problem.  I would ordinarily think that this might have something
to do with the fact that I'm running things on localhost, which can
sometimes have some weird effects -- but everything else in OpenACS
appears to work just fine, so I think that it's a  localized bug in
the bboard admin stuff.

Any ideas?

I upgraded my PostgreSQL version to 7.1.2 (again, with RPMs), and
everything now seems to work just fine.
