As you begin to use PostgreSQL, you will rely on others for help, either through the documentation or through the mailing lists. Consider contributing your knowledge back. If you learn something which is not in the documentation, write it up and contribute it. If you add features to the code, contribute them. Even those without a lot of experience can provide corrections and minor changes in the documentation, and that is a good way to start. The pgsql-docs@postgresql.org mailing list is the place to get going.
