There's one QOL extension that I haven't seen anyone else implement: dimensional analysis. I can declare a column is an integer. Why not an integer that expresses feet? Why shouldn't I be able to write SELECT 1inch + 1cm and get a correctly computed length? Why can't the query parser help me avoid nonsense like SELECT 1kg + 1hr? All this stuff is pretty straightforward to add and would help avoid avoidable mistakes.
