I got a report from someone using pg_upgrade coming from PG 8.3 ---
turns out we didn't rename toast tables to match the new relfilenode in
pre-8.4, so the attached applied patch avoids the check for these cases.
This check is new in pg_upgrade for 9.1.

Restructure pg_upgrade checks because pre-8.4 Postgres did not rename
toast file names to match the new relfilenode.
