title: How to Give A Postgres User SuperUser Previllege Through docker-compose?
body: <p>This is my docker-compose file section for postgres container. These settings are fine, but my django app requires this user to have superuser previlleges through this command inside postgresql.</p>
  
  <pre><code>ALTER ROLE project_admin SUPERUSER;
  </code></pre>
  
  <p>How can this be accomodated inside this docker-compose file?</p>
  
  <pre><code> db:
    image: postgres:latest
    container_name: project-db
    environment:
     - POSTGRES_USER='project_admin'
     - POSTGRES_PASS='projectpass'
     - POSTGRES_DB='project'
  </code></pre>
