Imran Zaheer: PostgreSQL Recovery Internals

30. Dezember 2025 - 6:30

Modern databases must know how to handle failures gracefully, whether they are system failures, power failures, or software bugs, while also ensuring that committed data is not lost. PostgreSQL achieves this with its recovery mechanism; it allows the recreation of a valid functioning system state from a failed one. The core component that makes this possible is Write-Ahead Logging (WAL); this means PostgreSQL records all the changes before they are applied to the data files. This way, WAL makes the recovery smooth and robust.
