How are the clustering options coming along with PostgreSQL? The last time I looked into there weren't any multi-master solutions out of the box, but there were a bunch of separate implementations that mostly seemed to be half-baked.

It's my understanding that the Postgres team has decided to change their historical stance of considering clustering solutions outside the scope of the core project, but I'm unclear exactly how far that has come.

The variety of different 3rd party implementations in various states of maturity make this a bit tedious to sort through.

That said, I always pick PG for my personal projects. I just have a hard time getting sign-off on it from my corporate overlords for anything at work.
