I notice that you many joins in there. If the query can't be simplified, you probably need to boost the join_collapse_limit and from_collapse_limit quite a bit. If planning time goes through the roof in that case, you may need to enable geqo -- this is what it's intended to help. If you try geqo, you may need to tune it; I'm not familiar with the knobs for tuning that, so maybe someone else will jump in if you get to that point. -Kevin
