I don't follow Postgres too much and I saw the tweet by Peter van Hardenberg first. It's great to see the enthusiasm for the project.
It's likely that 9.5 or even 9.6 will actually see the real significance of this new feature. I don't know how solid the implementation is but once its in the wild and these missing features are added to bring it to parity with MongoDB and others, and the bugs have been fixed, it will be a great solution for a NoSQL database instead of MongoDB and others.
That is significant and worthy of celebrating. This will also give MongoDB and others another yardstick to stay on top of their game.
