If you have any technical question or encounter any problem you can e-mail to: firstname.lastname@example.org and expect e-mail answer in less than a day. As the user-base of internet product is very vast, and users support other users, internet will be capable of giving technical support to billions of users easily. Email support is much more convenient than telephone support as you can cut and paste error messages, program output etc.. and easily transmit to mailing list/newsgroup.
In the near future, PostgreSQL organisation will be selling technical support to large/small companies, the revenue generated will be used for maintaining several mirror sites (web and ftp) around the world. The revenue will also be used to produce printed documentation, guides, textbooks which will help the customers. The profits will also be used to construct buildings/class-rooms and offer technical courses in database administration/management and conduct annual user conferences. This would help PostgreSQL organisation to stand on its feet.
