The presentation does discuss some of the more popular features of 9.5, but as a whole it discusses the state of PostgreSQL as of 9.5. That includes features, community, and process. I think the most important item is the user interaction. At each presentation location I brought up the fact that PostgreSQL has no bug/issue tracker. This led to the long threads currently being discussed on pgsql-hackers about having an issue tracker. If PostgreSQL 9.5 doesn't land for another 9 months (it will be sooner; we are at Beta) and instead we received proper tracking of issues, I would be plenty happy.
I used to do a lot more technical speaking, but lately I am finding more satisfaction in engaging users. One of the things that I have found out about the user groups is a lot of the attendees do not subscribe to the lists; they are community members by usage not contribution. However, without our users PostgreSQL is just another once upon a time (remember XFree86?) project. Thankfully, PostgreSQL is very good about listening to its users and knowing that engaging them is going to lead to a better product.
Good times! I am off to go rock climbing.
P.S. Another round of thanks to Bruce Momjian; without him the presentation would have taken a lot more time!
