Folks, we have been getting:
FATAL 1: my bits moved right off the end of the world!
Recreate index pg_attribute_relid_attnam_index.

Oh, that old thing :-(. If you have a way to reproduce this from a
standing start (virgin database) I'd be very interested to see it.
We've seen sporadic reports of this problem for a long time but no
useful debugging information. I think that the problem might be fixed
in 7.1, but I can't be sure when I've never had any field failure under
the microscope.

I understand that this is a b-tree index problem but how does
one recreate pg_attribute_relid_attnam_index?

See REINDEX. Also consider updating.
