March 5th 2005 at 3 PM in Copenhagen. That’s the exact time and place Daniel Gustafsson’s career took an unexpected turn, pivoting from operating systems to databases. At LinuxForum that day, Daniel had planned to meet up with the FreeBSD community, but a chance session about Postgres by Bruce Momjian completely blew his mind. By the time Daniel was on the train back to Malmö, he was already compiling Postgres. In this episode of Talking Postgres with Claire Giordano, Postgres major contributor and committer Daniel Gustafsson of Microsoft walks us through how he got his start as a developer and in Postgres—starting with his earliest computing memories of a hulking steel box in his family’s living room in Sweden. Also part of Daniel’s story: guitar tuning software. And curl!

What’s it like to lead Postgres engineering at a cloud giant like Microsoft Azure? In this episode of Talking Postgres, host Claire Giordano chats with Affan Dar, VP of Engineering for Postgres at Microsoft. Affan’s team is behind the Azure Database for PostgreSQL managed service and also contributes extensively to the upstream Postgres open-source project. Affan walks us through his career journey—from his first job as an embedded systems engineer, to navigating the shift between engineering and management, to leading one of the largest Postgres engineering teams in the world. He shares the strategy behind Microsoft’s investments into Postgres, explores how massive cloud fleets are influencing the future of Postgres, and shares what keeps him up at night.

Have you ever achieved something remarkable because someone planted an idea in your mind? In this episode of Talking Postgres, host Claire Giordano talks with Andrew Atkinson—a Rails developer and Postgres user whose journey to becoming a published author began with a simple seed of inspiration. Andrew’s story started with an internal presentation on how to tackle tricky scalability challenges in Rails, grew into a Postgres conference talk at PGConf NYC—and ultimately evolved into his book, High Performance PostgreSQL for Rails. Also in this episode: what does cheese have to do with Postgres? Is writing a good way to think? What’s the connection between Postgres and swimming to Antarctica? And which chapter of his book does Andrew love the most?
