 #### PostgreSQL
 
 AWX requires access to a PostgreSQL database, and by default, one will be created and deployed in a container, and data will be persisted to a host volume. In this scenario, you must set the value of `postgres_data_dir` to a path that can be mounted to the container. When the container is stopped, the database files will still exist in the specified path.
