Webinar: Postgres 19 in practice: what shipped, what got cut, and how to test it
Postgres 19 is running later than usual, and several headline features were reverted during the beta cycle. Lukas walks through what is actually shipping, what got cut and why, and how to test the release candidate before the final release on November 19.
Recorded live on October 15, 2026, the day Postgres 19 RC1 was released.

In detail, we walk through
- What bloat actually is, and how REPACK CONCURRENTLY removes it online instead of VACUUM FULL
- WAIT FOR LSN and read-your-writes on replicas
- pg_plan_advice for controlling query plans, pg_stash_advice for pinning them, and how pg_stat_plans 2.1.1 shows which advice reproduces a plan
- Monitoring improvements such as pg_stat_lock and fast-path lock statistics, and the EXPLAIN ANALYZE timing changes Lukas contributed
- Changed defaults (JIT off, lz4 TOAST compression), sequence replication, LISTEN/NOTIFY scalability, the release schedule (RC2 on November 12, final release on November 19), and how to test the release candidate
