    How AI is changing software development with Simon Willison

    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.” Previously on Talking Postgres: Talking Postgres podcast Ep 30: AI for data engineers with Simon Willison Links mentioned in this episode: Blog: Simon Willison’s BlogProject page: Datasette, for finding stories in dataGitHub repo: sqlite-utilsBlog post: Release of alchemy-utils 0.1a0 (featuring Postgres & DuckDB)Blog post: There are no lossless transformations of natural-language text, by Sophie AlpertPodcast episode: The Open Weight Revolution with Simon Willison, on Oxide and FriendsPodcast episode: An AI state of the union, on Lenny’s Podcast Wikipedia: Winchester Mystery HouseIdea in Mythical Man-Month: Conceptual integrityBlog post: SQLite compressed text-history prototypes, by Simon WillisonTools: Simon’s miscellaneous tools repoIn this episode, we covered: 00:00 Intro & music 04:00 A week of work before breakfast 09:12 Red-green TDD makes agents exercise every line 14:42 A million lines mean nothing if you don’t understand it 18:28 Finding low-hanging fruit among open PRs & issues 22:07 Getting work done while walking the dog 23:01 Gold standard: “Could I explain this to somebody else?” 28:27 Slop proxies add no value at all 30:49 Aggressive nitpicking reviews 35:01 Everything in software engineering is about trade-offs 41:16 Racoon heist game is only fun for 1 minute 15 seconds 43:46 New Year’s resolution to be more ambitious 48:11 You have to learn to throw things away 51:57 Features are cheap.

    Working on Postgres after 13 years on SQL Server with Panagiotis Antonopoulos

    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.

    How I got started running a Postgres user group with Jeremy Schneider

    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.

    From MemSQL to HorizonDB, an engineer's journey with Adam Prout

    What does it take to make Postgres and Azure fit together cleanly, like puzzle pieces? In Episode 39 of Talking Postgres, Adam Prout—distinguished engineer at Microsoft and a founding architect of Azure HorizonDB—joins Claire to trace his engineering journey from MemSQL to Postgres. We dig into shared-storage architecture and how HorizonDB pushes more work into the storage layer; why the team chose Rust; and what “good systems programming” looks like when being paranoid is a feature, not a bug. Along the way: startup vs big company tradeoffs, and how working on databases exposes you to so many interesting parts of computer science.   Previously on Talking Postgres: Talking Postgres Ep29: How I got started leading database teams with Shireesh ThotaLinks mentioned in this episode: Blog post: Announcing Azure HorizonDB, by Charles Feddersen & Affan DarCMUDB talk: HorizonDB: Co-Designing Postgres and Azure for Cloud-Native OLTP, by Adam ProutResearch paper: Socrates: The New SQL Server in the CloudProduct page: Azure HorizonDBVideo of POSETTE 2025 talk: Scaling Postgres to the next level at OpenAIBlog post: Scaling PostgreSQL to power 800 million ChatGPT users, by Bohan ZhangBlog post: Supporting ChatGPT on PostgreSQL in Azure, by Affan Dar, Adam Prout, & Panagiotis Antonopoulos Docs: Azure Database for PostgreSQLGitHub repo: pgrxDiscord: PostgreSQL Hacking serverConference: PGConf.dev 2026Conference Schedule: PGConf.dev 2026 Schedule

    How I went from Oracle to Postgres (with a big NoSQL detour) with Gwen Shapira

    It’s rare for developers to genuinely love their database, so why does Postgres earn that kind of loyalty? In Episode 38 of Talking Postgres, Gwen Shapira, co‑founder of Nile, joins Claire to trace her path from operating Oracle at scale, through a long NoSQL chapter, to co‑founding a Postgres company that wasn’t originally meant to be one—after discovering how much Postgres quietly gets right. Gwen shares how she spun up on Postgres after years with other databases (shout-out to the Happiness Hints and a strong sense of curiosity), and why Postgres has made her appreciate Codd. We also touch on blogging as a career catalyst, the upcoming PGConf.dev conference (where a lot of PG20 work gets discussed, and where we’ll celebrate 30 years of Postgres)—and the #1 rule of consulting: it’s always the consultant’s fault.   Previously on Talking Postgres: Talking Postgres Ep15: My Journey to Explaining Explain with Michael ChristofidesTalking Postgres Ep24: Why mentor Postgres developers with Robert HaasTalking Postgres Ep30: AI for data engineers with Simon WillisonLinks mentioned in this episode: Gwen’s company: NileArdent Performance Computing blog: PostgreSQL Happiness HintsBook: Just Use Postgres! by Denis MagdaGitHub repo: HypoPGWikipedia page: Codd’s 12 rulesBlog post: Transaction Isolation in Postgres, by Gwen ShapiraPodcast: Postgres.FMDiscord server: PostgreSQL Hacking Upcoming conferences & talks mentioned: Conference: PGConf.dev 2026 on May 19-22 in Vancouver CanadaConference Schedule: PGConf.dev 2026 scheduleCFP deadline: PGConf.dev Community Discussion Sessions deadline on 14 Apr 2026Conference: PGConf EU 2026 in Valencia SpainLinkedIn post: PGConf.dev 2026 conference t-shirt, celebrating 30 years of PostgresPOSETTE 2026 talk: The Rise of PostgreSQL as the Everything Database, by Varun DhawanPGConf.dev 2026 Panel: Real-Time Patch Idea EvaluationPGConf.dev 2026 Roundtable: Unexpected Successes & Epic Failures by PostgreSQL committersCalendar invite: LIVE recording of Ep39 of Talking Postgres to happen on Wed May 06, 2026

    Building Postgres services on Azure with Charles Feddersen

    Why does SQL feel so approachable to some developers, and why do some of them end up spending their careers in the data layer? In Episode 37 of Talking Postgres, Charles Feddersen, who leads product for Postgres at Microsoft, joins Claire to talk about building Postgres services on Azure. We explore his path from classic ASP apps on Microsoft Access to distributed Postgres with Citus, the moment he installed pgAdmin and got pulled deeper into Postgres, and what it takes to build for the many different ways people rely on Postgres today—from Flexible Server and Azure HorizonDB to developer tooling—and why it’s important to support the upstream Postgres open source project.

    Why it's fun to hack on Postgres performance with Tomas Vondra

    Why would anyone willingly spend weeks chasing a slow query, knowing they might hit dead ends along the way? In Episode 36 of Talking Postgres, Tomas Vondra—Postgres committer and long‑time performance contributor—joins Claire to explain why hacking on Postgres performance is not just hard, but also fun. We dig into the process of investigating why queries are slow, how iteration and “wrong turns” are part of performance work, and why Tomas prefers meaningful performance puzzles over toy problems. Along the way, we talk about using benchmarks to build an understanding of a problem. Tomas also shares how even small changes in code can have outsized impact when that code is used a lot, and how the mathematics embedded in the Postgres query planner/executor makes the work especially rewarding.

    How I got started with DBtune (& why we chose Postgres) with Luigi Nardi

    Are self-driving databases the Waymos of the future? In Episode 35 of Talking Postgres, Luigi Nardi—founder and CEO of DBtune and Stanford researcher—joins Claire Giordano to explore his journey from academic research to Level 5 autonomous database tuning. We dig into Luigi’s early days with a Commodore 64, how he began his PhD in Paris before he had learned to speak French, and how "professor privilege" in Sweden helped him bootstrap his startup. You’ll learn why the DBtune team chose database tuning and Postgres as their focus, what the Jevons paradox means for the future of developers, and how the “Level 5” vision fuels the DBtune team’s work toward a truly self-driving system.   Previously on Talking Postgres: Talking Postgres Ep30: AI for data engineers with Simon WillisonTalking Postgres Ep23: How I got started as a developer & in Postgres with Daniel GustafssonLinks mentioned in this episode: CFP: POSETTE: An Event for Postgres 2026’s CFP closes on Sun Feb 1, 2026 @ 11:59pm PSTVideo of POSETTE 2024 talk: Autotuning PostgreSQL on Azure Flexible Server, by Luigi NardiVideo of PGConf India 2025 talk: ML for Systems and Systems for ML, by Luigi NardiPGConf India 2025: Round Table Discussion about AIOxide and Friends podcast: Engineering Rigor in the LLM AgeWikipedia: Jevons paradoxWikipedia: Neuro-symbolic AIConference: PGDay Lowlands (Boriss Mejías calls it the second-best Postgres conference in Europe)Calendar invite: LIVE recording of Ep36 of Talking Postgres to happen on Wed Feb 18, 2026
