It turns out that not defining a structure to your model makes it easy to prototype but difficult to query the data afterwards.

Which is why MongoDB is awesome for teaching and building new stuff but horrible for reports, metrics, and scaling.

Who said that they moved to relational model? They chose PostgreSQL because it's JSON support makes it also a superb document database.
