Looks really cool. I was first thinking it saves the JSON with the new Postgres JSON support, but saving it as relational data is even more impressive! I'd say

Looks really cool. I was first thinking it saves the JSON with the new Postgres JSON support, but saving it as relational data is even more impressive! I'd say if the OPTIONS would return a JSON Schema (+ RAML/Swagger) instead of the json-fied DDL, it would be even more awesome. With a bit of code generation this would be super-quick to integrate in the frontend then.
