How I got started as a developer & in Postgres with Daniel Gustafsson

Who knew an aptitude test could recommend a career as a DBA—and get it right? In Episode 44 of Talking Postgres, PostgreSQL significant contributor Karen Jex walks Claire through her path from Oracle DBA to Postgres consultant, solution architect, and now senior software engineer at Snowflake. My favorite bits: a project switched to Postgres when nobody knew how to install it, faking it as the Postgres expert, and the culture shock of building your own HA and backups. Plus: the warm welcome at PGConf EU 2019 that pulled Karen into the Postgres community; the new Buddy Program at PGConf EU 2026; and moving to the French Alps for the love of mountain biking.

How does a fix for psql tab completion turn into 25 years of contributing to Postgres? In Episode 43 of Talking Postgres, Peter Eisentraut—PostgreSQL committer, core team member, SQL standards contributor, and Chief Architect of Database Servers at EDB—joins Claire to trace that journey. We dig into how scratch-your-own-itch development drew him in, why “the things you do, people welcome them” kept him coming back, and how Postgres changed as it grew from a small database community into a massive ecosystem where, from the Postgres mailing list perspective, “most of the user base is silent.” Plus: what it feels like when code you commit goes straight to everybody who uses Postgres, and the implications of the EU Cyber Resilience Act.

What’s your gold standard for deciding whether AI-written code is ready for production? In Episode 42 of Talking Postgres, Simon Willison—creator of Datasette, co-creator of Django, and prolific open-source developer—joins Claire to share how AI is changing the way he builds software today. We dig into why his test for shipping AI-generated code is “Could I explain this to somebody else?”, how engineering management skills can be surprisingly useful when managing AI agents, and how the bottleneck is no longer writing code but understanding it. Also: personal credibility, deep research, the Winchester Mystery House, slop proxies, and Simon’s observation that “Features are cheap. That doesn’t mean you should build them all.”

What happens when a database engineer spends 13 years on SQL Server and then starts working on Postgres? In Episode 41 of Talking Postgres, Distinguished Engineer Panagiotis “Panos” Antonopoulos of Microsoft joins Claire to share what surprised him most about making that transition. We explore why Postgres felt familiar from the start—and what shocked Panos about the clean and lean Postgres codebase. We also dig into how public mailing lists and AI can help explain why design decisions were made, why more people are asking “why not Postgres?”, and the shared-storage architecture behind Azure HorizonDB.

Intensely local user groups have been part of Jeremy Schneider's story from the start—from Linux meetups at a Michigan coffee shop to a closet server running an Oracle database nobody knew anything about. In Episode 40 of Talking Postgres, Postgres engineer and Seattle Postgres User Group co-organizer Jeremy Schneider joins Claire to share how community led him to Postgres after 15 years with Oracle—and why "it's like I was born to be here." Plus: the newly-updated Postgres Happiness Hints poster, advice for starting your own user group, and his POSETTE 2026 talk on CloudNativePG.
