October 2024 monthly summary for vshn/appcat-user-docs. Key deliverable: a prominent data-loss warning added to the PostgreSQL user management documentation to alert users that dropping the database will cause data loss and to back up data before proceeding. This improves safety messaging and reduces operational risk for users handling critical PostgreSQL databases.
