Hm, did this start happening immediately after the other problem?
That would suggest that you've got worse problems than just a corrupt
index. You weren't by any chance running with full_page_writes = off
were you?

You could get past the startup failure with pg_resetxlog, but it's not
clear whether you'd have a consistent database afterward. What I'd
suggest first is saving a copy of the entire $PGDATA tree for forensic
purposes (not to mention being able to go back to that state if you need
to).

Is there any chance of letting someone else have a look at the database
contents? Otherwise you're going to have to do your own sleuthing to
figure out what went wrong ...
