My understanding is that pg_log contains flags about which transactions
have committed, from which is inferred what tuples are valid.  So
theoretically you could set "all transactions have committed" in pg_log
and pick out the tuples you like from the tables (after having gotten past
the horribly corrupted indexes).  But that seems like a pretty complicated
undertaking in any case.
