If you want to know whether or not the buildfarm will have problems
due to VACUUM failing to get a cleanup lock randomly, then I suggest
that you use an approach like the one from my patch here:

I recently tried it again myself. With the gizmo in place the tests
fail in exactly the same way you've had problems with on the
buildfarm. On the first try, even.
