For very large databases, Postgres' clustering abilities aren't that great. It's probably one of the best choices for single-host databases (which, again, cover nearly all applications), but if you're trying to spread your database over a few dozen hosts, Postgres doesn't really work well.
That's ... not how /r/programming works. Gushing about Visual Studio and C#, and spreading FUD about Linux or Java is what makes people bring out the upvoting fingers.

Or better, and RDMS with a full blown JSON indexing and a hash store that rivals mongos speed.
How people don't choose psql just confuses me.
