It's similar, but written in JavaScript instead of Haskell. As someone who prefers the type safety and performance of Haskell, I'll be sticking with PostgREST.

To get both GraphQL and standard PostgREST endpoints (as well as a few other tools), this starter kit is really nice and fires right up with docker-compose:

Very similar! The project was originally inspired by PostgREST - the main difference being that it uses GraphQL as the API layer rather than REST.

Edit: Apparently this is based on https://github.com/postgraphql/postgraphql which makes sense!
