I'll go further and say that the entire upgrade should be atomic. If
any part of the upgrade fails, no changes should take place at all.
The very first thing the upgrade should do is to start a transaction.
If there's a failure at any point, a rollback should be issued. If it
gets to the end, a commit can be done.
That is does not do this already makes little sense to me, as it's
easy enough to do.
