OK, but why? When the clusters are stopped they are the same, you are
running the same initdb on both matchines, and running the same
pg_upgrade. What would cause the difference, other than the Database
System Identifier, which we can deal with? I don't think we can
guarantee they are the same, but what would guarantee they are
different?
