POSETTE: An Event for Postgres 2025 is back for its 4th year—free, virtual, and packed with deep expertise. No travel needed, just your laptop, internet, and curiosity.
This year’s 45 speakers are smart, capable Postgres practitioners—core contributors, performance experts, application developers, Azure engineers, extension maintainers—and their talks are as interesting as they are useful.
The four livestreams (42 talks total) run from June 10-12, 2025. Every talk will be posted to YouTube afterward (un-gated, of course). But if you can join live, I hope you do! On the virtual hallway track on Discord, you’ll be able to chat with POSETTE speakers—as well as other attendees. And yes, there will be swag.

- Voila—talks for that stream
How to watch & how to participate on Discord
Here’s how to tune in—and how to participate in the conference.
How to watch the livestreams

What’s new in POSETTE 2025
If you attended POSETTE last year (or back when it was called Citus Con), you might be wondering, what’s different this year?
In many ways, the POSETTE playbook is the same: useful and delightful Postgres talks in a virtual, accessible format. But here’s what’s new:
- New website: And, a new domain too: PosetteConf.com
- Only 2 keynotes: instead of 4 keynotes last year. We’re honored that Bruce Momjian & Charles Feddersen accepted the invitation to be keynote speakers. Each keynote will be repeated twice.
- 58% speakers new to POSETTE: 26 out of 45 speakers (58%) are brand new to POSETTE
- New livestream hosts: 3 of the 7 livestream hosts are brand new to hosting POSETTE livestreams: welcome to Adam Wølk, Derk van Veen, & Thomas Munro
- Same name: The POSETTE: An Event for Postgres name is here to stay—and we still love the name
