It'd be considered, but whether it'd be accepted would have to depend on the size of the performance boost, its portability (how many platforms/scenarios do you actually get a boost for), and the extent of bloat/uglification of the code. I can't personally get excited about something that only helps if your server is starved for RAM --- who runs servers that aren't fat on RAM anymore? But give it a shot if you like. Perhaps your analysis is pessimistic. regards, tom lane
