Is this happening during WAL replay? If so, you could probably get
the database to start by doing pg_resetxlog. No guarantees about how
consistent your data will be afterwards :-( ... but with a little luck
you'll be able to run pg_dump and compare with your backup. I'd
definitely recommend an initdb and reload after you get a dump that
seems sane.
