What You’ll Learn

During this session, you’ll learn practical strategies to safely manage schema (DDL) and data (DML) changes in PostgreSQL environments. We’ll cover essential techniques to help you plan, execute, and verify changes without compromising stability or performance:

  • Prepare and test migrations

Use version-controlled, idempotent scripts and test thoroughly in staging with rollback plans.

  • Apply DDL changes safely

Introduce schema updates incrementally, avoid locking operations during peak hours.

  • Handle DML operations wisely

Use batching for updates, avoid long transactions, and stage complex changes with CTEs or temporary tables.

  • Execute and monitor effectively

Automate rollouts, monitor live metrics, and validate results to ensure data integrity and system stability.
