As far as the *target* cluster is concerned, I have no sympathy for
someone who messes with its contents before running pg_upgrade.
That's an RTFM matter: you're supposed to upgrade into a virgin
just-initdb'd cluster.
However, it would be nice if pg_upgrade supported transferring from a
*source* cluster that didn't have the postgres DB.
What about creating a new, single-purpose database in the source
cluster and then removing it again after we're done?
