Completing a PostgreSQL backup does not prove it can be restored, says lab guide

A DEV Community article argues that a finished backup job is only partial evidence, since recovery also requires accessing the backup, restoring it to a suitable environment, validating the data, and returning the service within acceptable limits. It presents a hands-on PostgreSQL lab exercise that creates synthetic data, produces a logical dump, and restores it into a new database for comparison. The author stresses that the exercise is a walkthrough rather than a measured benchmark or a full disaster-recovery plan, and does not cover operating systems, object storage, secrets or external services. The piece also notes that logical dumps are only one component of a recovery strategy, alongside physical backups, WAL archiving and managed-service features.
