I heard through the grapevine of some people currently investigating
performance problems on busy FreeBSD systems, possibly related to the
postmaster pipe. I suspect this patch might be a part of the solution
(other patches probably needed to get maximum value out of this patch:
reuse WaitEventSet objects in some key places, and get rid of high
frequency PostmasterIsAlive() read() calls). The autoconf-fu in the
last version bit-rotted so it seemed like a good time to post a
rebased patch.
