GraphpostgresQL: A GraphQL Extension for PostgreSQL

Here's an active project that does something similar (introspects your postgres schema and runs a graphql API on top): https://github.com/graphile/postgraphile

Prisma is also interesting (but pulls more logic out of the DB).

My question with this type of logic-in-the-DB framework is how people are managing schema migrations and what infra they're running on as it's clearly a little less charted than, for instance, deploying a rails app (what I know). I really like the DRYness of writing the schema in one place and having that flow automatically into strongly typed models, API, etc with correct auth logix. This always seems like too much boilerplate with ActiveRecord and controllers.
