    The Making of POSETTE: An Event for Postgres with Teresa Giacomini & Aaron Wislang

    The Making of POSETTE: An Event for Postgres with Teresa Giacomini & Aaron Wislang

    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.

    My Journey to Explaining Explain with Michael Christofides

    My Journey to Explaining Explain with Michael Christofides

    Did you know that sometimes the fastest way of doing something is not having to do it at all? In this episode of Path To Citus Con, the podcast for developers who love Postgres, Michael Christofides joins Claire Giordano to chat about his journey to explaining explain (or should we say EXPLAIN!?) Michael shared his origin story as a mathematician and his first experience with Postgres before walking us through co-founding a Postgres company and now co-hosting a podcast. Like many in the Postgres community, he is opinionated in the best way possible! We even learned about his passion for BUFFERS and why he believes everyone should use them. This session also dives into Michael’s belief in the importance of Postgres documentation. Because great documentation can be worth its weight in Gold, especially when the going gets tough.

    Becoming expert at using PostgreSQL with Chris Ellis

    Becoming expert at using PostgreSQL with Chris Ellis

    You have to find what works for you and Chris Ellis has never been the kind of person that could go and sit in a library—for Chris, the most productive Postgres place is in a coffee shop. In this episode of the Path To Citus Con podcast for developers who love Postgres, Chris Ellis joined Claire and Pino to chat about his path to becoming more (and more) expert at using PostgreSQL. Curiosity may have killed the cat but it’s taken Chris places, beginning as a 5 year old playing with QBASIC. Chris shared his journey to becoming a developer, an electronic engineer, a builder, and a PostgreSQL user. This session also delves into Chris’s work as a Postgres conference speaker (and organizer!) Importantly, we spent time remembering Simon Riggs, Postgres leader extraordinaire. RIP.

    Spinning up on Postgres & AI with Arda Aytekin

    Spinning up on Postgres & AI with Arda Aytekin

    Everywhere you look, people are talking about AI. From Copilot to ChatGPT to Postgres’s powerful AI capabilities (think: pgvector), AI is everywhere. In this episode of Path To Citus Con, for developers who love Postgres, Arda Aytekin joined Claire and Pino to chat about spinning up on Postgres and AI. Arda shared his origin story in mechanical engineering and data science before walking us through vector databases, pgvector, and azure_ai. Arda is one of the creators of the azure_ai extension, so the conversation delves into the azure_ai integration between Azure Database for PostgreSQL and Azure AI Services. Also discussed (of course) was—Responsible AI.

    From developer to PostgreSQL specialist with Derk van Veen

    From developer to PostgreSQL specialist with Derk van Veen

    The best days are when things don’t go as planned. Derk van Veen joined Claire Giordano and Pino de Candia on this podcast for developers who love Postgres—to discuss his journey from Java developer to PostgreSQL specialist and DBA. From his first days with DB2 and Oracle, to his work with Postgres, Derk shared how he learned about databases. And how a very smart colleague would break the database on purpose, to give Derk the tough job of fixing it. Another topic: what to do when you need to jump on a problem but your heart rate doubles? What will it take to get that magical feeling of fixing something in the database? And a segue into sharing your expertise as a speaker at Postgres conferences. Because it’s always about the why.

    My Journey into Performance Benchmarking with Jelte Fennema-Nio & Marco Slot

    My Journey into Performance Benchmarking with Jelte Fennema-Nio & Marco Slot

    No one likes benchmarking. But it can be one of the highest impact things you do. Jelte Fennema-Nio and Marco Slot joined Claire Giordano and Pino de Candia on this podcast for developers who love Postgres—to discuss their journeys into performance benchmarking. And how it can change the course of your career. Do you need to find bottlenecks in your Postgres? Do you want to build skills with database benchmarks? There are many lovely benchmarking tools in the Postgres world: HammerDB, pgbench, YCSB, BenchBase, perf, & more. And in addition to running benchmarks themselves—asking the right questions, introspection, and profiling matter just as much.
