Tom Lane 0bd7af082a Invent recursive_worktable_factor GUC to replace hard-wired constant. ... Up to now, the planner estimated the size of a recursive query's worktable as 10 times the size of the non-recursive term. It's hard to see how to do significantly better than that automatically, but we can give users control over the multiplier to allow tuning for specific use-cases. The default behavior remains the same. Simon Riggs Discussion: https://postgr.es/m/CANbhV-EuaLm4H3g0+BSTYHEGxJj3Kht0R+rJ8vT57Dejnh=_nA@mail.gmail.com		4 years ago
