You're right if you're directly exposing your Databse-driven-GraphQL API to the client. If you use GraphQL to power your REST APIs this is less of an issue. On the other hand, tightly coupling your database to a client doesn't always have to be a bad thing. If you outscale a single Postgres Database with Hasura you can add read replicas. If that still doesn't work you can add Yugabyte to the mix to scale further.
