Talking Postgres with Claire Giordano

It’s always a good day if you see a pelican. In Episode 30 of Talking Postgres with Claire Giordano, open source developer Simon Willison—creator of Datasette and co-creator of Django—joins to explore how AI is useful for data engineers today. We move past the hype and boosterism to dig into example after example: structured data extraction, alt text and accessibility, safety and security (aka the fiddly bits), and why Postgres’s fine-grained permissions are such a good fit for AI-powered workflows. Also: Pulitzer-worthy data tooling, the science fiction of the 10X engineer, agents, MCP, RAG, the multitude of models, and why Simon spends so many waking hours on the jagged frontier of AI.Links mentioned in this episode:Blog: Simon Willison’s WeblogBlog: Simon’s Willison’s TIL - Things I’ve LearnedPodcast episode: Working in public on open source with Simon Willison and Marco SlotProject page: Django Web FrameworkProject page: Datasette, for finding stories in data GitHub repo: llm CLI tool and Python libraryDemo: Language models on the command-line w/ Simon WillisonBlog post: OpenAI’s new open weight (Apache 2) models are really good, by Simon Willison Podcast episode: Accessibility and Gen AI podcast with guest Simon WillisonBlog post: New dashboard: alt text for all my images, by Simon Willison Keynote talk: Big Opportunities in Small Data, by Simon Willison at Citus Con: An Event for Postgres 2023 Blog post: How OpenElections Uses LLMs, by Derek Willis Blog posts tagged with pelican-riding-a-bicycle on Simon Willison’s Weblog Blog post: No, AI is not Making Engineers 10x as Productive, via Colton Voege, featured on Simon’s weblogGitHub repo: pgvector extension to PostgresCal invite: LIVE recording of Ep31 of Talking Postgres to happen on Wed Sep 17, 2025

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).Links mentioned in this episode:Newsletter: Postgres WeeklyCooperpress: List of newslettersNewsletter: Latest issue of Postgres Weekly on Jun 19, 2025Newsletter: Postgres Weekly issue with horrible graphicNewsletter: Very first issue of Postgres Weekly on Mar 13, 2013Newsletter: Ruby Weekly, the first Cooperpress newsletterBook: Beginning Ruby Third Edition, by Peter CooperPodcast episode: How I got started as a developer (& in Postgres) with David RowleyFeed reader: FeedbinGitHub repo: feedbin/feedbinFeed reader: FeederEmail testing software: LitmusGitHub repo: MGML markup language for emailPaper: The Design of PostgresGitHub repo: PGRX for building Postgres extensions in RustPodcast news: Podnews.net for daily briefings about podcastsWikipedia page: BBC MicroWikipedia page: ZX SpectrumCal invite: LIVE recording of Ep29 of Talking Postgres to happen on Wed Jul 9, 2025

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!Links mentioned in this episode:Open source project website: postgresql.orgWebsite: Bruce MomjianVideo of talk: Building Open Source Teams at FOSDEM 2023Slides: FOSDEM talk on Building Open Source TeamsWikipedia: John C.

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.Links mentioned in this episode:Podcast episode: Becoming a Postgres committer with Melanie Plageman Slide: PGConf EU 2024 talk by Claire Giordano about Contributions to Postgres, including new mentoring programBlog post: New Mentoring Program for Code Contributors in Postgres, by Robert HaasBlog post: Postgres Mentoring Program Updates, by Robert Haas Discord invite for PostgreSQL Hacker Mentoring server: https://discord.gg/bx2G9KWyrYBio: Margo Seltzer, the PGConf.dev 2024 keynote speakerVideo: PGConf.dev 2024 panel discussion about Making PostgreSQL Hacking More Inclusive with Amit Langote, Masahiko Sawada, Melanie Plageman, & Robert HaasMailing list: PostgreSQL HackersUpcoming Conference: PGConf.dev 2025, the annual PostgreSQL Development Conference happening in Montreal Canada on May 13-16, 2025Blog: Postgres committer Tomas Vondra’s Blog - Look for [PATCH IDEA] Video of Talk: CMUDB Database talk about PostgreSQL Optimizer Methodology, by Robert HaasPodcast episode: How I got started as a developer & in Postgres with David RowleyCalendar invite: LIVE recording of Ep25 of Talking Postgres podcast to happen on Wed Mar 12, 2025 with guest Dawn Wages of the Python developer community

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.Links mentioned in this episode:Docs: Azure Database for PostgreSQL – Flexible ServerGitHub repo for Durable Task Framework, the first open source project Affan worked onGitHub repo for pgvector open source extension to PostgresDocs: Elastic cluster feature in Azure Database for PostgreSQL – Flexible Server, based on CitusGitHub repo for Citus open sourceBlog post: Postgres horizontal scaling with elastic clusters on Azure Database for PostgreSQL, by Adam WølkGitHub repo for DiskANN open sourceDocs: How to enable and use the DiskANN index for Azure Database for PostgreSQL – Flexible ServerBlog post: Think of language models like ChatGPT as a “calculator for words” by Simon WillisonBlog post: What’s new with Postgres at Microsoft (updated 2x/year typically)Video of Talk at Microsoft Ignite: Improving accuracy of GenAI apps with Azure Database for PostgreSQL by Maxim Lukiyanov (Microsoft), Jay Yang (UBS), & Orhun Oezbek (UBS)CFP: POSETTE: An Event for Postgres 2025 CFP open until Feb 9 2025Calendar invite: LIVE recording of Ep23 of Talking Postgres podcast to happen on Wed Jan 15, 2025 with guest Daniel Gustafsson

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.Links mentioned in this episode:Wikipedia: Tom Lane (computer scientist)Wikipedia: HP 9800 seriesCMU CS Department Coke Machine historyWikipedia: Honeywell 316Wikipedia: Teletype Model 33Wikipedia: Hydra (operating system)Wikipedia: William WulfWikipedia: Jon Bentley (computer scientist)Wikipedia: Mary Shaw (computer scientist)Wikipedia: UsenetGitHub: postgres commit by tglsfdcArticle: The Mars 2020 Engineering Cameras and Microphone on the Perseverance Rover: A Next-Generation Imaging System for Mars Exploration by J.N.

Ever wonder how driving a forklift at a cheese factory could lead to a career in databases? Postgres committer David Rowley joined Claire Giordano on this episode of the Talking Postgres podcast (formerly Path To Citus Con) to share his story about how he got started as a developer and in Postgres. Could an unexpected job lead to your dream career? Does speeding things up give you a buzz? How could an idea from a hike become a Postgres patch? And what is the importance of doing the research before you submit a proposal to the Postgres mailing list? Also discussed: resources available to start your Postgres journey such as books, blogs, videos, and the pgsql-hackers mailing list.Links mentioned in this episode:Wikipedia: Acorn ComputersPostgreSQL Mailing List Archives: David’s first email: Possible problem with EXTRACT(EPOCH FROM TIMESTAMP)Google Usenet: Larry Page’s Java question from Jan 7, 1996Blog: Speeding up sort performance in Postgres 15 by David RowleyBlog: What’s new in the Postgres 16 query planner / optimizer by David RowleyBook: The Art of PostgreSQL by Dimitri FontaineBook: The Art of SQL by Stéphane Faroult, Peter RobsonBook: The Art of Writing Efficient Programs: An advanced programmer's guide to efficient hardware utilization and compiler optimizations using C++ examples by Fedor G.

It’s not a conference unless you can confer, right? POSETTE organizers Teresa Giacomini and Aaron Wislang join Claire Giordano on the Path To Citus Con* podcast to share backstage perspectives on the making of POSETTE: An Event for Postgres. How do you feel about captions: love or hate? Should livestream talks be pre-recorded or presented live? Why rename from Citus Con to POSETTE? Where did the inspiration for POSETTE come from? And can the hallway track at a conference actually be fun—if it is virtual? Also discussed: Avett Brothers lyrics, the surprising number of POSETTE speakers with chickens, and the existential question of whether the work in organizing a conference is worth it.*[Update: July 2024] Path To Citus Con has been renamed to Talking Postgres.
