How it works...

Many people ask questions such as How can this be free?, Are you sure I don't have to pay someone?, or Who gives this stuff away for nothing?

Open source applications such as PostgreSQL work on a community basis, where many contributors perform tasks that make the whole process work. For many of these people, their involvement is professional, rather a hobby, and they can do this because there is generally great value for both the contributors and their employers alike.

You might not believe it. You don't have to, because it just works!
