Slightly off topic, but possibly relevant to the overall process: those are the same conditions under which I would love to see the rows inserted with the hint bits showing successful commit and the transaction ID showing frozen. We currently do a VACUUM FREEZE ANALYZE after such a load, to avoid burdening random users with the writes. It would be nice not to have to write all the pages again right after a load.
