PostgreSQL: PostgreSQL recovery drill evidence
A replicated standby is mistaken for a complete backup strategy. Compare independent backups, archived WAL and an isolated restore test with the recovery objective.
Environment and inputs: PostgreSQL 18 documentation baseline; views, extensions and permissions vary across versions and managed services.
Failure scenario
A replicated standby is mistaken for a complete backup strategy. Confirm the cause before choosing a fix.
Evidence to collect
Compare independent backups, archived WAL and an isolated restore test with the recovery objective. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Document a tested restore path and keep replica health separate from recoverability evidence. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for postgresql recovery drill evidence using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
