Hmm ... I wonder if this is telling us that our patch here was
incomplete?
http://archives.postgresql.org/pgsql-committers/2006-11/msg00004.php

At the time we thought this failure could only occur during _bt_pagedel
but you have evidently got a case where a split is failing. It might
just be garden-variety index corruption, or it might be a real bug.

Is this database sufficiently small and non-proprietary that you could
send me a filesystem copy of it (a tarball of all of $PGDATA including
the WAL files)?
