Most of the time, we hear about PostgreSQL success stories, but reality can be quite different. After a decade of production experience, it's time to share my nightmare stories. Let's explore together what happens when everything goes wrong in the world of database management.

This talk will walk you through database near-disasters that I've encountered over the years. Those cases are real ones where I had to play the firefighter, for customers, partners, and my own production. For each scenario, we'll discuss the initial symptoms that raised alarm bells, the troubleshooting processes we employed, and the ultimate resolutions that saved the day (most of the time).

Since we always learn from our mistakes, these experiences offer valuable lessons. Thanks to these PostgreSQL horror stories, you'll learn how to prevent or solve similar issues.
