Nice you added the check to pg_upgrade, but I assume a pg_dumpall
restore is going to fail pretty badly, e.g. any pg_* object assignment
will fail. I guess there isn't much we can do to fix that.
The pg_dumpall will work but will throw a warning. A restore will fail to recreate any pg_* roles and there could be follow-on errors from that, of course.
I had pg_dumpall throw an error initially, but based on discussion that was considered too harsh.
Thanks!
