You could do some tests to see it working. – Frank Heikens Jun 27 '12 at 5:16

PostgreSQL automatically uses multiple cores to support multiple database connections, if you have multiple cores. No further configuration is necessary.

Postgres allocates one process per client, and, generally speaking you will only see that process go to 100% of 1 of your cores. To increase throughput you need to use more clients/connections.

good point, apart from 8.2 being a bit outdated. – dezso Jul 12 '12 at 15:41
Oh, I didn't even see that was the version that came up in Google. The text is the same even in the current 9.3 dev version: postgresql.org/docs/devel/static/connect-estab.html – ers81239 Jul 12 '12 at 15:54
