Yes, I would like a copy of your script.
I just found and fixed a problem that could lead to this kind of failure
(reference to an already-deleted CLOG entry). However, I'm not sure
that the problem I fixed could affect VACUUM itself. Please update from
cvs (make sure you get src/backend/utils/time/tqual.c v 1.46) and then
see if you still see the problem. If you do, a backtrace from the point
where elog() is called would be really helpful.
