Topics include the feature freeze process, key features that made it in (AIO worker auto-tuning, online table repacking via pg_squeeze integration using logical decoding, shared memory API improvements), and features that didn't make the cut (write combining, resizable shared_buffers). The panel also covers the long-term multithreading roadmap, collaboration dynamics in open source development, time zone challenges, and plans for Postgres 20 including latch/wakeup refactoring and concurrent index creation. ## Full article daily.dev links to this article rather than hosting it.
