There's a lot of negativity here for understandable reasons given the success of SQL empirically. But I'd encourage everybody to read the home page https://edgedb.com/. This project is not trying to replace SQL as its primary goal, it's trying to build a data modeling and query interface on top of Postgres that meshes well with modern applications that have hierarchical data akin to what you'd model with GraphQL. Major kudos for trying to rethink and improve upon things -- I'm sure it wouldn't be too hard to stick an SQL backdoor in there for the laggards too ;).
