Force pg_upgrade's to preserve pg_class.oid, not pg_class.relfilenode.

Browse Source 
Toast tables have identical pg_class.oid and pg_class.relfilenode, but
for clarity it is good to preserve the pg_class.oid.

Update comments regarding what is preserved, and do some
variable/function renaming for clarity.
