Postgres has no special functionality regarding processors. Each
connection is handled by a separate process. A multi-CPU aware OS is
then free to run those as best it sees fit.
Given that databases are typically RAM or I/O bound as they scale,
adding more processors to a machine is not a silver bullet. Performance
is extremely dependent on the situation. If you really need a number to
satisfy a PHB, try 42.
