When Databases Disagree: Smarter Conflict Management in PostgreSQL, Gary Evans #FOSSASIA Summit 2026

Logical replication in PostgreSQL powers migrations, upgrades, CDC pipelines, and active/active architectures—but at its core, it is a flexible mechanism for transporting ordered data changes.

This talk explores major PostgreSQL 18 improvements to logical replication conflict handling, including explicit conflict detection, classification, and observability. Through live demos, see how conflicts that were once silent or vague apply failures are now visible, structured, and measurable.

Learn why PostgreSQL intentionally avoids built-in conflict resolution, allowing higher-level tools to implement safe and predictable behavior for blue/green deployments, migrations, and multi-active systems. We’ll also look ahead at the future of PostgreSQL logical replication and conflict management.
