Proper configuration monitoring and validation is critical - check shared buffers, max connections, and other key parameters regularly

Be aware of sub-transactions in Postgres - they use a fixed-size cache that can overflow and cause performance issues if not managed properly

Consider partitioning strategies carefully - choose appropriate partition keys, validate partition creation/cleanup processes, and monitor partition management overhead

Standardize logging practices - use consistent log formats, separators and retention policies. Consider tools like PG Badger for log analysis

Implement proper backup and archiving strategies - test restores regularly and maintain point-in-time recovery capabilities

When troubleshooting performance issues:

• Check for connection spikes/leaks
• Look for long-running transactions
• Monitor replication lag
• Review index usage
• Validate vacuum processes

Communication between teams is critical - DBAs, developers and ops need aligned processes and expectations

Consider database encryption needs carefully - evaluate options like TDE, column-level encryption, and key management requirements

For high availability:

• Plan failover processes
• Test recovery procedures
• Monitor replication status
• Document operational procedures

Keep up with Postgres versions and extensions - plan upgrades carefully and test thoroughly before production deployment
