"select * from pg_language" shows only internal, c, and sql.  I haven't
altered the server code at all.  I don't know what a plug-in is in the
PostgreSQL context, so I assume I'm not using any of those, either.  :)
  I've got several apps installed, but the only one I've run at all is a
PHP-based one, Serendipity.  It just runs "regular" SQL statements.

I haven't altered the config at all (but see below).  The settings in
postgresql.conf indicate it's using a deadlock timeout of 1 second (1000
ms).

I know; I'm open to suggestions on what information would be useful.
One setting I did just change in postgresql.conf affects logging; it's
now logging all statements via syslog.  I hope that I'll be able to find
the offending statement in the log the next time it hangs.

I intend to switch to 8.0, but I'd rather not do so immediately if I can
help it.
