That is an odd failure. That check was added in PG 9.1 and this is the
first time I am seeing this failure.

The check is to make sure that once we have created all the user schema
details in the new cluster, that there are the same number of objects in
the new and old databases.

Obviously there are a different number in your case here, but I don't
know why those would be different, and in fact, because we have never
hit this, there isn't even any debug output that shows the source of the
difference.

If I send you a patch can you compile it and send back the debug output
it produces?
