Due to popular requests, I have updated the results on page 2 with
Postgres-9.1.1 on Linux numbers.

Scientific Linux was the fastest of all operating systems once there were more
processes running than cores.
It was also the less stable. I discovered more than once the machine was
completely frozen (blank screen, no keyboard or network response). Even a NMI
couldn't change anything.
