That's *very* odd, because it works for me. Is the same true of both
those duplicate rows, or did you only try the one with nonzero xmax?
I think there must be something we don't know about the states of those
rows. Could you grab pg_filedump from http://sources.redhat.com/rhdb/
(note: right at the moment that server seems to be down, but I suppose
it'll be up soon) and dump out page 53101 of this table? Usually
I find "-i -f" to be the most informative formatting option.
