Symptom & Impact

Applications lose database access because PostgreSQL remains in failed state.

Environment & Reproduction

Debian 13 database servers after package upgrade and automatic service restart.

Root Cause Analysis

Extension mismatch, config syntax errors, or file permission issues block startup.

Quick Triage

Review service status and recent PostgreSQL logs for startup error details.

Step-by-Step Diagnosis

Validate configuration files and check data directory ownership and disk status.

Solution – Primary Fix

Repair configuration or extension dependencies and restart PostgreSQL cluster.

Solution – Alternative Approaches

Promote a standby node and perform controlled remediation on the failed primary.

Verification & Acceptance Criteria

Database service is active, replication healthy, and application checks pass.

Rollback Plan

Revert package version or restore database backup if integrity checks fail.

Prevention & Hardening

Run pre-upgrade compatibility tests for extensions and custom PostgreSQL settings.

Related Errors & Cross-Refs

Related messages include FATAL could not open configuration file and invalid checkpoint.
