You could try running pg_resetxlog (see contrib if pre-7.3; in 7.3 it's
standard).  That should let you start the database, but keep in mind
that any transactions completed shortly before the crash might be
missing or partially applied.  Don't trust the data too much until
you've checked it.  And definitely do a dump and reload...
