It is true that CPU affinity is designed to prevent the dump of valuable
CPU cache. My thought is that if you are trying to prevent CPU
contention, you could use CPU affinity to prevent 2 postmaster processes
from running simultaneously on the same die. Am I out to lunch here?
I've not worked with CPU affinity before, so I'm not familiar with the
intimate details.
