There isn't one. But there also isn't really a primary use case for postgres, as compared to mysql. It's just a pretty pleasant to use nosql database. Easy clustering, first-class changefeeds, a somewhat-confusing query-system, runs in the current working-dir by default means it's dead-simple to set up for development. No fire-and-forget write. Reminds me a bit of firebase, but free and open-source. If you're in a position where changefeeds or nosql are important, you should probably give rethinkdb a look.
