Actually, the dump doesn't record tuple OIDs (unless you specifically
ask for them), it just dumps source sql.  When this gets reloaded
you get an equivalent database, but not the same database, that you
started out with.

That's why I've presumed you can't run the WAL against it.

If you and I are wrong I'd love to be surprised!
