That's the problem. People sometimes need to access those files from
the file system level. There are just too many variations of why they
need that I don't think there is any way to anticipate them. If someone
comes up with a better idea, I am all ears, but seeing as nothing better
has appeared since it was first written, I think we need to move forward.

I will add these items to the TODO list, unless someone else votes. I
think they are too important to have in /contrib (and we moved
pg_resetxlog/pg_controldata from /contrib in 7.3) and I think
relfilenode is better than OID so people start using that rather than
OID for filename mapping.
