This discussion has gone on for two years now and meandered into
different directions. There have been a number of interesting
proposals and patches in that time but it's not clear now what patch
is even under consideration and what questions remain for it. And I
think this message from last November is the last comment on it so I
wonder if it's reached a bit of an impasse.
I think I would suggest starting a fresh thread with a patch distilled
from the previous discussions. Then once that's settled repeat with
additional patches, keeping the discussion focused just on the current
change.
Personally I think these kinds of optimizations are important because
they're what allow people to use SQL without micro-optimizing each
query.
