I will say this. Most other databases are more forgiving of bad
queries. Make a bad query and postgresql is more likely to punish you
for it. But I've seen production oracle servers make pretty bad query
plans too because someone used a non-selective sub-select that the
planner couldn't work around.
I love postgresql, and I think the query planner has made leaps and
bounds since I started working with it. But it is not designed to run
bad sql quickly.
