Oh, and while I'm bitching: it seems like there is hardly any part of the partitioning code in which the comments aren't desperately in need of a copy-editing pass. They are just chock-full of misspellings, grammar that is faulty enough to make the meaning unclear, and/or errors of fact. An example of the latter is the repeated claims that the basic partitioning functions belong to the planner. Maybe that was true at some stage of development; but AFAICS the logic in question now lives in src/backend/partitioning/, which I would not think is part of the planner. regards, tom lane
