You do nothing. The kernel will take care of giving each backend
process the idlest processor. PostgreSQL is multiprocess, as opposed to
the multithreaded model of MySQL and others, so PostgreSQL itself cannot
do anything about the scheduling; it is left to the operating system.
Just be sure to use an SMP kernel.
