@maropu I think it's too tricky if rewriting plan with `planMapping` is recursive. The reason is that, `WidenSetOperationTypes` does the work by traversing the plan tree twice. I made the plan rewriting method more general, so that `WidenSetOperationTypes` only need to traverse the plan tree once, and now the logic is simpler. Please take a look, thanks! ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
