This is nothing vital but i'm a bit confused by this, and it makes me curious. I use docker-compose to spin up an instance of postgresql container to handle every configurable storage in

dagster.yaml

, but even though I declared

environment:
      - POSTGRES_DB=dagster
      - POSTGRES_USER=dagster
      - POSTGRES_PASSWORD=dagster

I don't see any table named

dagster

inside postgres or in the schema. What is the function of

POSTGRES_DB

if not for pointing which table to use by

dagster_postgres.run_storage

, etc?
