I don't see any reason to think this is a planner regression. The
rowcount estimates are pretty far off in both versions; so it's just a
matter of luck that 9.0 is choosing a better join order than 9.3.
I'd try cranking up the statistics targets for the join columns
(particularly domain_id) and see if that leads to better estimates.
