Remarkable similar to my own history with Postgresql, which I started using in ~1998 at the time of their first public release. Postgresql documentation has indeed been the exemplar for all software, open source or not. It's been the SQL textbook I've relied on. With the steady addition of features, it's gotten much more complex, and there will come a time when using just the documentation won't be enough to learn how to use Postgresql to full advantage. With release of 9.5 we might be there now. Perhaps the logical extension of the documentation is some form of coursework to enable users to learn the DB systematically. I haven't looked into it, this might already be offered.
