So had we all :-(. It just plain doesn't work in 8.1.*, and will be
disabled in 8.1.4 --- see discussion last week. It might or might not
get resurrected in 8.2, depending on how messy it seems to be to fix.
Anyway, that explains your "heap_clean_redo: no block" failure. I think
you're stuck risking a pg_resetxlog to try to get back into the
database. If that results in a hopelessly corrupt database, we can try
modifying the WAL replay code to not consider this a fatal error, and
see if that produces anything we can use for debugging. I'm glad this
isn't your only copy of the database ...

It sounds like the DB is too big to consider shipping anywhere anyway.
As long as you're comfortable doing stuff like pg_filedump and modifying
the code to get more debug info, we can proceed without getting into the
question of remote access.
