FWIW, the only occurrences of that specific message text are in
PageIndexTupleDelete and PageIndexMultiDelete, so you can be pretty sure
that this is just a corrupted-index problem.  Once you've identified
which table has the problem, a REINDEX should fix it.

I concur with the other comments that a crash with fsync off might well
have allowed more corruption than just this to sneak in, though :-(
