PostgreSQL Performance Optimization Guide This guide introduces a systematic path for index tuning, slow query analysis, connection pool sizing and database observability. Use it as a starting point for production database performance reviews.
Use cases
Useful for teams handling Database issues and needing a clear troubleshooting and delivery workflow.
Problem background
A systematic method for index optimization and query tuning, from slow query analysis to connection pool configuration.
Troubleshooting steps
Confirm impact and recent changes, collect logs, configuration and metrics, then apply fixes from low to high risk.
Command examples
Replace sample resource names with real values and store passwords, tokens and keys in environment variables.
Risks
Before production changes, confirm backups, access boundaries, change windows and rollback paths.
Rollback plan
Keep original configuration and release versions; roll back config, images or database changes if metrics degrade.
Deliverables
Root-cause notes, key commands, remediation steps, verification results and follow-up recommendations.
