******* SESSION DETAILS

Talk 1 by Sahil Sharma
Title: PG monitoring in Cloud native landscape

Abstract: In this technical session, we will build a complete, proactive monitoring solution from scratch. Using CloudNativePG (CNPG) as our orchestrator and a local Kubernetes environment, we will walk through the architecture of a high-fidelity observability stack.
What we will build and demonstrate:

• Deploying CNPG: Setting up a production-ready Postgres cluster in K8s with native monitoring enabled.
• The LGTM Integration: Connecting Prometheus for metrics, Loki for logs, and Grafana for a "single pane of glass" view.
• Log Parsing: Using the OpenTelemetry Collector to collect Postgres logs.
• Closing the Loop: Configuring Alertmanager to send real-time Slack notifications for slow queries or infrastructure failures occur.

Attendees will leave this session with a practical blueprint and the code necessary to turn their database from a silent dependency into a transparent, observable, and proactive part of their infrastructure.

Talk 2 by Bernd Reiß
Title: The PostgresChecker: Hunting Use-after-free Bugs in PostgreSQL
Abstract: This talk presents the PostgresChecker: A static analysis tool for finding use-after-free bugs in PostgreSQL. It discusses a novel approach for identifying memory-managing functions in the PostgreSQL source code and how they were used to implement a static checker.
