This name is more illustrative, and little bit cleaned code. CMD_SELECT_UTILITY is mix of CMD_SELECT and CMD_UTILITY. It allows PREPARE and parametrizations like CMD_SELECT. But execution is like CMD_UTILITY by own utility routine with explicit dest receiver setting. This design doesn't need to introduce new executor and planner nodes (like ModifyTable and ModifyTablePath). Regards Pavel > Regards > > Pavel > > >> Regards >> >> Pavel >> >
