Talking Postgres with Claire Giordano

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

What do conference planning, hacking weddings, and cat-free coding sessions have to do with Postgres?

In this engaging discussion, Rob Emanuele, a principal engineer at Microsoft and co-creator of the VS Code extension for PostgreSQL, shares his unique journey from music to software development. He dives into the challenges of using Postgres at planetary scale with the Microsoft Planetary Computer and reveals his insights into GitHub Copilot's role in modern coding. From thoughts on agent-driven workflows to the importance of feedback in building tools, Rob also highlights how creativity in music influences his engineering approach.

What do chess clocks, jazz, and Postgres replication have in common? In Episode 32 of Talking Postgres, solution architect Boriss Mejías shares how the idea of “interconnectedness”—inspired by Douglas Adams—can help you untangle complex Postgres questions. We explore OpenAI’s approach to scaling Postgres, how Postgres active-active mirrors Sparta’s dual kingship, and how a holistic approach can reveal the behavior of synchronous replication. Also: Beethoven’s 17 drafts, and why chasing perfection can hold you back. Listen to learn more about Boriss, Postgres, and the fundamental interconnectedness of all things.Links mentioned in this episode:Podcast Ep32 of Talking Postgres: What went wrong (& what went right) with AIO with Andres FreundPodcast Ep03 of Talking Postgres: Why give talks at Postgres conferences with Álvaro Herrera & Boriss Mejías:  Wikipedia: Dirk Gently’s Holistic Detective Agency, by Douglas AdamsTalk at PGConf NYC 2025: Scaling Postgres to the Next Level at OpenAI, by Bohan ZhangVideo of PGConf.dev 2025 talk: Scaling Postgres to the Next Level at OpenAI, by Bohan ZhangTalk at PGConf NYC 2025: Improved Freezing in Postgres Vacuum: From Idea to Commit, by Melanie PlagemanTalk at PGConf NYC 2025: Database Modeling to Study the New York Jazz Scene, by Boriss MejíasJazz Club in NYC: Patrick’s Place in HarlemVideo of PGConf EU 2024 talk: Sparta’s Dual-Kingship and PostgreSQL Active-Active, by Boriss Mejías Video of POSETTE 2025 talk: Postgres Storytelling: Cunning Schema Design with Creative Data Modeling, by Boriss Mejías & Sarah Conway Talk at FOSDEM PGDay 2024: High Availability Configurations Are Very Common for PostgreSQL, But How Do You Investigate Performance Problems When the Standby Can’t Keep Up? by Boriss Mejías and Derk van VeenConference: PGDay Lowlands 2025, the second year of this “second-best Postgres conference in Europe” Conference Schedule: upcoming PGConf EU 2025 in LatviaWikipedia: Chess clockBook: Daily Rituals, by Mason CurreyArticle: It Takes Two to Think, by Itai Yanai & Martin J.

Six years, a prototype, and a brief multi-layered descent into “wronger and wronger” design—what does it take to land a major architectural change in Postgres? In Episode 31 of Talking Postgres, Andres Freund—major contributor, Postgres committer, and lead of the Asynchronous I/O project—shares the wins, the missteps, and why he thinks AIO definitely took too long. We dig into io_uring in Linux, direct I/O, streaming reads, technical leadership, and exactly when is the right time to stop working on a prototype. If you’ve ever wondered how big architectural changes happen, or why they sometimes take years, this episode is for you. Links mentioned in this episode:Talking Postgres podcast: How I got started as a developer (& in Postgres) with Andres Freund & Heikki LinnakangasRelease Notes: PostgreSQL 18 release notes News: PostgreSQL RC 1 Released on Sep 04 2025Wikipedia page: io_uringPostgreSQL: Join the PostgreSQL Hacking DiscordVideo of talk: What went wrong with AIO by Andres Freund at PGConfdev 2025Commit: Add core asynchronous I/O infrastructure to PostgreSQLWiki page: AIO project in PostgreSQL with state, sub-projects, and work still to be doneUpcoming Talk: AIO in PG 18 and Beyond at PGConf NYC on 30 Sep 2025Upcoming Talk: AIO in PG 18 and Beyond at PGConf EU on 23 Oct 2025Wikipedia page: XZ Utils backdoor discovery by Andres FreundCal invite: LIVE recording of Ep32 of Talking Postgres to happen on Wed Oct 8, 2025

From dreaming of driving a bus to leading database engineering at Microsoft. In Episode 29 of Talking Postgres with Claire Giordano, Shireesh Thota traces his path to becoming CVP of Azure databases—rooted in a love of math, early BASIC programming, and a certainty that he’d become an engineer. We dig into the shift from engineer to manager (if only people came with documentation); why it’s so important for Microsoft to contribute to the PostgreSQL open source project—not just consume it; and whether Shireesh has a favorite database (hint: it better be Postgres.)Links mentioned in this episode:Blog post excerpt: Why we have a Postgres open source contributor team at MicrosoftPodcast episode: Leading engineering for Postgres on Azure with Affan DarVS Code Marketplace: New VS Code extension for PostgreSQLPOSETTE 2025 talk: Introducing Microsoft’s VS Code extension for Postgres by Matt McFarlandLinkedIn post: PGConf.dev 2025 talk on “The trouble with extensions” by Marco SlotPodcast episode: How I got started as a developer (& in Postgres) with David RowleyBook: Who Moved My CheeseCal invite: LIVE recording of Ep30 of Talking Postgres to happen on Wed Aug 6, 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

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.
