Improve Documentation: Database Maintenance Responsibilities

# Improve Documentation: Database Maintenance Responsibilities ## Link No link ## Describe the problem The current documentation clearly explains the shared responsibility model for security, but it provides very little information about atabase maintenance. Users are left uncertain about key operational responsibilities, including: - Who handles PostgreSQL updates for security patches and regular version updates? - Will I be notified if there is a security patch (if i need to do it manually)? - Which maintenance tasks do I need to perform myself (e.g., `VACUUM`, `REINDEX`, `ANALYZE`, `CLUSTER`, `PARTITIONING`)? - Are there any checks for data integrity or corruption (`pg_checksums` or similar)? - Can I schedule the timing of daily backups to align with my data retention policies, I would like to make a backup before my cron job deletes old records? This lack of clarity makes it difficult for users to plan maintenance, schedule cron jobs, and ensure database performance and reliability. ## Describe the improvement The documentation should include a dedicated section on database maintenance, covering: 1. **Database Updates** – Clarify responsibilities for applying PostgreSQL security patches and regular updates, including notification policies. 2. **Maintenance Tasks** – List key tasks such as: - `VACUUM` / `VACUUM FULL` - `REINDEX` - `ANALYZE` / Auto-Analyze - `CLUSTER` tables - `PARTITIONING` / table sharding - Data integrity and corruption checks Explain which are automated, which require manual intervention, and their typical scheduling. 3. **Backups & Recovery** – Explain how daily backups can be scheduled and if not, at what times they occur. Providing this guidance will help users understand which maintenance responsibilities fall on them versus the managed service and how to schedule tasks like cron jobs safely.
