Hmm, what Postgres version is this? Can you get a stack trace from
the startup process crash?
The only simple way out of this is to delete the presumably-corrupt
WAL log by running pg_resetxlog. That will destroy the evidence
about what went wrong, though, so if you'd like to contribute to
preventing such problems in future you need to save a copy of everything
beforehand (eg, tar up all of $PGDATA). Also you might have a corrupt
database afterwards :-(
