I am quite late to the party, but PostgreSQL 10 has been released three weeks ago! We've been waiting for this release for quite some time now, given that this version marks the start of many new features in the system. Kaarel Moppel of Cybertec has a nice list for developers as well as for DBAs, so nice actually that I won't even bother making one myself! Head over there, install, practice, and be amazed!

Oh, and also, this.
