Upgrading PostgreSQL on AWS RDS with (almost) zero downtime

Every database admin’s nightmare & every manager’s dream: Database upgrades without an outage. But is it really so difficult?

We will explore the challenges of the process including preparation, schema changes, the upgrade, and finally data consistency verification. It’s all about consistency and readiness, isn’t it?
