update-manager fails because of postgresql-server-dev-9.1

After removing the package, it works.

The cause of the problem was found by fetching the log output using "ubuntu-bug ubuntu-release-upgrader-core" but I think it's problematic that none of the upgrading tools show the cause of the problem when it's known...

Cheers,
Benjamin
