I don't think you can assume that would hold true for an open-source database. Unlike a commercial database, it's trivially easy to notify developers about a bad query plan. With a commercial database you'd have to open a support ticket and hope they actually use that info to improve the planner. Here you need just send an email to this list and the developers will at least see it, and will usually try and fix the issue. -- Jim C.
