To answer my own question that doesn't work. I've kept playing around with different
paramaters with different variables but I can't find anything except disabling seqscans.

This is really annoying, because *all* of my queries suddenly slowed down at the same
time. What can I do? Is there something I can change in the source to have nested loops
seem cheaper? I haven't found anything.
