These ones maybe?

I think it was only around SUM(numeric), and you'll need to scroll down a
bit to find it as it's mixed in with a load of window agg tests. At the
time it was the only forward transition function that I had added any
overhead to, so I think it was the only one I bothered to test at the time.
However, I do remember benchmarking the bool_and and bool_or changes after
I rewrote the way they worked and also found the same as you... no
difference, I just can't find the post with my results... Though it sounds
like Tom found the same as me so I don't think it's worth me looking any
more for them.
