Well, not only that, but the machine is currently writing to the
postmaster log at the rate of 2-3MB/s. ISTM some kind of sleep
(perhaps growing exponentially to some limit) would be a good idea.
Well, since the code has always behaved that way and no one noticed
before, I don't think it's worth anything as complicated as a variable
delay. I just stuck a fixed 100msec delay into the accept-failed code
path.
Seems worth mentioning that bgwriter sleeps 1 sec in case of failure.
(And so does the autovac code I'm currently looking at).
There is probably a good case for a shorter delay in postmaster, though.
