There are multiple ways to get a GraphQL API on top off a Postgres database. If you want to have a GraphQL abstraction layer that runs as a hosted service and needs almost no code, have a look at StepZen. You can build a GraphQL API for the Postgres database by following the docs here. StepZen introspects the database (using stepzen import postgresql) and let it create the schema for you based on all the tables and columns of your database. Including a set of queries to get started with.
