Or if I get ambitious, dig into the code myself if I can figure out where to
start...

If nothing else, you should bring it up on -hackers and ask to have this added as a TODO. It seems like a worth-while addition to pg_dump/ restore to me...

To answer another of your emails in this thread... a LAZY vacuum of the entire database will read every table and index in the database. Wanting to read the entire database to check for corruption is no reason to do a VACUUM FULL. Also, if you're curious about restore time for your upgrade, you should be doing the restore to an 8.1.4 database, not to your current version. There's been a ton of performance improvements made. In fact, I'm wondering if constraint checking in restore has been improved...
