I'm not sure that Rust is really a good example. While promising, the language itself and its standard library are still immature and subject to a huge amount of disruptive change on an ongoing basis.

I've had some experimental code I wrote in Rust become essentially unusable after only a few months due to significant language and standard library changes. I sure hope that somebody wouldn't spend time on a PostgreSQL library for it until the language itself becomes more stable. They'd be wasting a lot of time and effort if they did try to write such a library now.

Rust is a perfect example: http://blog.mongodb.org/post/56426792420/introducing-the-mon...

So are many other newer languages and frameworks. See vibe.d (http://vibed.org/) for D which has only database drivers for MongoDB and Redis.
