As per PFC's comment, if connections/sec is a bottleneck for you then
the answer is to use persistent connections. Launching a new backend
is a fairly heavyweight operation in Postgres. It sounds like there
may be some system-level constraints affecting the process creation
rate as well, but it's silly to spend a lot of effort on this when
you can so easily go around the problem.
