Was that a system-wide crash, or just a backend crash? It seems
to me that your kernel must have lost that file for you; Postgres
wouldn't have gone out and deleted it.

This used to work pre-7.1, and it seems to me it should still work;
relcache.c is being inappropriately paranoid about finding the file.
I have corrected that part of the problem.
