May I suggest that Appendix E also includes release date for each
release, and also lists tentative/planned features for future releases
(say: in 7.5, win32 port and 2-phase commit; in 8.0, ...; etc).
This is like Appendix D of the MySQL documentation. It gives
outsiders/beginners like me a better picture of how PostgreSQL has
progressed over time.
Thanks,
