Hmm. That would amount to saying that there are no global superusers
for D1, which might be a bit of a problem --- if local DBA paints
himself into a corner, you can't get him out. Backing up a cluster that
has not got global superusers would be a PITA too.
Still, I think you are right that we gotta think outside the box if
we're going to find a way to do this.
