... or the estimated dump size winds up being less than the actual dump size. But I understand your basic point. I was wrong about us running 2.4.2p2... we're using 2.4.5, so I can try maxdumpsize right now. But maxdumpsize seems like it is just a substitute for runtapes * tape_length. That is, it's directly used by the planner to decide what size to target. So bumping up maxdumpsize seems like the equivalent of lying about your tape size. What I'd like is for a nominal planner target size and then beyond that, if some dumps wind up not fitting, have a knob (say, overflow_to_holding=true or dont_skip=true or something) to allow dumps that would otherwise be skipped to go to holding disk instead. I'd even go as far as saying 'true' should be the default for such a knob even though that is different than the current behavior. I think skipping dumps is almost always a bad choice. I don't have code to implement this at the moment. But is there any future directions that might help in this area? Any other opinions?
