Thanks Sergey, I will try this too.

I think the bother here is that this statistics are pretty good (we do
analyse regularly and default_statistics_target is already 1000), but once I
start filtering the two tables the correlations alter quite a bit. I don't
think there is that much that can be done about that :)
