*Any* of the databases?  Since pg_index isn't shared it's difficult to
imagine a failure scenario that would wipe out all the databases in an
installation in this same way.

The error itself suggests that you've got a zeroed-out row in pg_index.
You could possibly recover by manually dropping the index in question,
if it's not a critical index.  What I'd try doing is starting a
standalone backend with the -P switch (ignore system indexes); if that
will let you in, then you'd be able to look through pg_index to try to
determine what's clobbered.
