Guide to POSETTE: An Event for Postgres, 2025 edition

POSETTE: An Event for Postgres 2025 is back for its 4^th 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.
