What drives someone to publish 600+ issues of a Postgres newsletter for over a decade? In Episode 28 of Talking Postgres with Claire Giordano, Peter Cooper—creator of Postgres Weekly—shares how his days of rustic programming and QBASIC fanzines on Usenet led to a newsletter empire that now reaches nearly half a million developers each week. We dig into the BBC's "big tent" editorial influence, an accidental business model that just worked, and the perils of "temporary" hacks. Plus: spam filters, a Photoshop addiction, and one very cheesy story (dairy-free).

How does a trek to K2 base camp in the Himalayas spark the idea for a database company? In Episode 27 of Talking Postgres with Claire Giordano, guest Peter Farkas—CEO and co-founder of FerretDB—shares the origin story of this open source MongoDB alternative. (Spoiler: “Ferret” wasn’t the original name). We dig into why Postgres was the obvious choice, what “true open source” means to Peter, and how FerretDB is now powered by the open source DocumentDB extension from Microsoft. Plus, why Hungarian Trappist cheese might deserve a footnote in database history.

What does it take to lead a global open source project like Postgres? In Episode 26 of Talking Postgres with Claire Giordano, we sit down with Bruce Momjian—co-founder and core team member of the PostgreSQL Global Development Group—to explore the art of leadership in a volunteer-run open source community. Bruce shares what “servant leadership” really means; how saying I’m sorry can help make problems go away; and how letting go of who-gets-the-credit can fuel collaboration. We also dive into Bruce’s origin story, from shaping Postgres’s early days to mastering the art of public speaking. Pro tip: if you see a man in a bow tie at a Postgres conference, be sure to say hello—it’s probably Bruce Momjian!

When I found out that Django developer and Python Software Foundation chair Dawn Wages has a chapter in her upcoming Domain-Driven Django book called “Just Use Postgres”, I knew we had to get her on the show. In this episode of Talking Postgres with Claire Giordano, Dawn breaks down why so many Python and Django developers have such an affinity for Postgres. And we dive into the Djangonaut Space mentoring program (where contributors launch), learn why “free as in puppies” beats “free as in cake” for open source vibes, and dig into why Python is the second-best language for everything.

Nobody works on an open-source project forever—eventually, people move on. So of course today's Postgres contributors want to see more developers join the project, pick up the torch, and continue to make Postgres amazing. Hence the importance of mentorship. In this episode of Talking Postgres with Claire Giordano, PostgreSQL major contributor and committer Robert Haas shares how he learned the ropes in Postgres by channeling “what would Tom Lane do” during patch reviews; why he launched the new PostgreSQL Hackers Mentoring program; and the intellectually stimulating care and feeding it takes to make Postgres thrive.

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?

It was not Tom Lane’s plan to become a computer person. Tom’s plan was to be a pinball machine designer. And yet for the last 26 years Tom has been one of the most prolific engineering contributors to Postgres. In this episode of Talking Postgres with Claire Giordano, PostgreSQL luminary Tom Lane walks us through how he got his start as a developer and in Postgres—including his time working on desktop calculators at HP. And how he has code running on Mars (and most of us don’t.) During Tom’s PhD studies at Carnegie Mellon, nobody told him databases were so interesting! It wasn’t until Tom needed a database to store stock trading information that he first got to work with Postgres. And that’s when Tom’s 26-year-long (and counting) Postgres story began.

If you could work on anything, would you quit your job to pursue it? Postgres committer and major contributor Melanie Plageman joined Claire Giordano on this episode of the Talking Postgres podcast (formerly Path To Citus Con) to share her story about becoming a Postgres committer. Melanie pivoted from IT consulting to open-source development, driven by her fascination with systems engineering and Postgres open source. What’s the secret to getting your patch committed? Feedback is a gift, but how willing are you to embrace it? How important is mentorship—and how important is it to ask for help? Even though crafting clear, concise emails to a technical community might not be easy, Melanie shows how empathy for other Postgres developers can help your work to stand out.
