    ...This all leads to gloriously low-latency user experiences, better developer experiences, and much increased productivity. Because of all this, GraphQL is typically used as a replacement for (or companion to) RESTful API services. PostgreSQL is the self-proclaimed “world’s most advanced open source database,” with each new release bring more amazing features and performance gains. Thinking of your database as a plain CRUD store is now an archaic viewpoint as modern PostgreSQL can do so much for you — from authorization with Row-Level Security (RLS, introduced in PG9.5), through Foreign Data Wrappers (FDW), to real-time notifications with LISTEN/NOTIFY.
