TALKS

Death by 50,000 Parameters: How pg_stat_statements Can Knock Over Your Patroni Cluster
Greg Clough, DRW
Think an observability extension can’t take down high availability? Think again. We’ll break down an edge-case production post-mortem where dynamic queries with tens of thousands of parameters caused pg_stat_statements hash table saturation, exclusive lock stalls, and cascading health check timeouts in Patroni (pre-4.1.4). Learn the mechanics behind the stall and how to protect your HA topology against similar blind spots.

A PostgreSQL 19 Whirlwind Tour
Jonathan Katz, Databricks
What's new in PostgreSQL 19? Quite a bit, and there's features for everyone who uses Postgres - app developers, DBAs, administrators, and more. In this presentation, we'll review new features in PostgreSQL 19, including new performance improvements that speedup reads from storage, better support property graph and bitemporal, and jsonpath queries, more OAuth capabilities, new monitoring data, and much more. We'll explore how these new capabilities build on previous PostgreSQL features, helping you understand how they fit into your daily usage.
