Hacking Workshop for April/May 2026

I'm planning to hold a single hacking workshop for April and May combined, covering Masahiko Sawada's talk, Breaking away from FREEZE and Wraparound, given at PGCon 2022. If you're interested in joining us, please sign up using this form and I will send you an invite to one of the sessions. Thanks to Sawada-san for agreeing to join us.

pg_plan_advice: Plan Stability and User Planner Control for PostgreSQL?

I'm proposing a very ambitious patch set for PostgreSQL 19. Only time will tell whether it ends up in the release, but I can't resist using this space to give you a short demonstration of what it can do. The patch set introduces three new contrib modules, currently called pg_plan_advice, pg_collect_advice, and pg_stash_advice.
