Ugh ... OID 2610 is pg_index.  It's a tad critical :-(

That's what I would have tried.  I'm afraid the DB is probably toast,
if that didn't work.  You could try tracing the startup with a debugger
to see where it goes wrong, but getting anything out of it is going to
require serious amounts of work, with no guarantee of success.  How
desperate are you?
