Also, my understanding is that they're feeding patches back to postgres, and want it to eventually run on stock postgres. But it's not clear to me how progress on that is going.
I was also surprised that UDR was removed, I didn't even realize it was deprecated.
I'm not actually using the product at all right now, but I've been watching on the website, because I want to use it eventually.
I'm kind of hoping it works with stock postgres before I jump in. But if not that, I think I at least want to wait for 9.6 support.
