What I find interesting is that PostgreSQL is slowly gaining features like that make it a good fit for many use cases of NoSQL datastores. With the BDR extension, it might even be possible to use PostgreSQL to implement an eventually consistent multi-master document store. Of course, none of this comes "out of the box", but it's interesting to see the two technologies becoming more like each other.
