Questions

## PostgreSQL: frequently asked

Managed Postgres or self-hosted?

Managed services handle backups, patching and failover for you and suit most teams. Self-hosting can make sense for cost, control or special extensions.

How do we know our backups work?

Restore them regularly to a separate environment and check the data. A backup that has never been restored is not proven.
