I think you're wasting your time to think about this now. By the time
7.3 comes out, we will have an entirely new approach to temp tables:
they'll be named with the same names the user sees, and live in
per-backend temp schemas to avoid name conflicts with permanent tables.
So any code based on working with the existing temp-name mapper will
be in the scrap heap before it can get released :-(

See unused_oids.
