Well, updating to the latest 7.4 version would be a very very good
move.  There are some very real and nasty data loss bugs in 7.4.5.
It's an in place update that requires only a few minutes of downtime.

I would guess you've got something like sort_mem set too high.

P.s. If you think PostgreSQL is hard to troubleshoot, I can't wait to
see you running Oracle.
