 There is a new problem on master (which affects 1.8 too, but it's a
 `RemovedInDjango19Warning` instead of a `RuntimeError`:
 {{{
 $ ./runtests.py postgres_tests

 hack in runtests.py] to omit the `postgres_tests` app when not running

 not in postgresql). I'm attaching a patch I experimented with, but there
