A simple fix is to teach pg_upgrade to issue "RESET SESSION AUTHORIZATION" immediately after connecting to a database.
Idon't see any downside of this currently - it seems that the only case where this wouldn't be a NO-OP is if someone
setROLE to to something else either per-database, per-user or both.
Actually, I'd like to provide an option for pg_dump and pg_restore to do that too (not by default, though). If people
thinkthis is a good idea, I could come up with a patch.
