Hi, maybe the document should be made clearer about how to use

[seepine]

Expect

Like postgres of hub.docker.com

docker run -d \
	--name some-postgres \
	-e POSTGRES_PASSWORD=mysecretpassword \
	-e PGDATA=/var/lib/postgresql/data/pgdata \
	-v /custom/mount:/var/lib/postgresql/data \
	postgres:16

Or docker swarm yml

version: '3.9'
services:
  db:
    image: postgres:16
    volumes:
      - /custom/mount:/var/lib/postgresql/data
    environment:
      POSTGRES_PASSWORD: example
    deploy:
      mode: replicated
      replicated: 5

Now docs
