Section 9.1 currently instructs students to skip the instructions to configure PostgreSQL in Spotify's "Getting Started" guide. However, future exercises depend on students' Backstage instances being able to persist data. It should be determined whether Backstage apps have a default database configuration or if this needs to be set up manually.
By default, Backstage sets users up to store data in-memory using sqlite3. I added a hint in a code change in #538 explaining how to change this setting to point to an on-disk location.
