Hello!  
I am building a forum using docker.  
I’m trying to use a remote database, but I have a few questions

1. Is it okay to use ppas (Postgres plus advanced server) ?
2. In this guide \> [Configure Discourse to use a separate PostgreSQL server](https://meta.discourse.org/t/running-discourse-with-a-separate-postgresql-server/46375)  
there is no migration procedure.  
If I run the “./launch rebuild app” or “bundle exec rake db:migrate” on the web server,  
it will the migration automatically performed on the remote database?

I look forward to your prompt reply.

Thanks

If you configure the DB settings, it’ll do as expected.

```plaintext
  DISCOURSE_DB_HOST: {{discourse_db_host}}
  DISCOURSE_DB_SOCKET: ''
  DISCOURSE_DB_USERNAME: {{discourse_db_username}}
  DISCOURSE_DB_PASSWORD: {{discourse_db_password}}
  DISCOURSE_DB_NAME: {{ discourse_db_name }}

```
