Infrastructure changes for recovery was an earlier version of hot
standby. That's all I was referring to here.

Hmm, well, not feeling that the patch is a priority for you seems
somewhat different than saying that it should be rejected outright.

I am glad to hear that Hot Standby is still on the road to being
committed, but even as a regular reader of -hackers I have to say the
process has been somewhat murky to me. Either there is a lot of
discussion that has been happening off-list, or there are long pauses
when either you or Simon aren't really corresponding and it isn't
obvious in whose court the ball lies. Based on what I've seen
on-list, I sort of thought that Simon was waiting for you to take the
next step by committing at least some portion of the patch. Needless
to say if you're both waiting for each other nothing will get done.
