You're the one poring over the specifics of what I've done, to my
consternation. I am not prepared to defend the patch at that level, as
I've made abundantly clear. I've called it a sketch, a proof of
concept half a dozen times already. I don't understand your difficulty
with that. I also don't understand how you can be so dismissive of the
benchmark, given the numbers involved. You're being unreasonable.
If I didn't write this patch, and I talked to people about this issue
at pgCon, I'm not sure that anyone would be convinced that it was a
problem, or at least that it was this much of a problem.
