Yes, this was an incredible development, and lead to hilarious projects like ToroDB (MongoDB API on top of Postgres), which ended up being faster and safer, with relations when you need them.

JSON columns can be incredibly useful and easy to understand for things like user preferences, without the hassle of a metatable.

Call this hilarious if you want, I think it's rather cool, thanks for the pointer. Once this is out of beta it will definitely be useful, if not already.

No doubt the best thing that has happened lately to Postgres as well!

And Postgres can do JSON with vastly more performance than Mongo:

If you're going to get on the "MongoDB was overhyped" bandwagon, you should probably not post links to performance comparisons you pulled off of an EDB Postgres website.

At least EDB used an inspectable and reproducable test. I think posting links to performance comparisons is fine when the performance comparison can be independently verified.

look at this article on why that benchmark was bullshit.

I suggest then that you get the latest versions of MongoDB and PostgreSQL and run that test and report back. Verifiable isn't the same as verified.

How about built in replication that isn't insane to setup and use? Might be a close second.
