PostgreSQL 19 SQL Is INSANE: Graph Queries, GROUP BY ALL & DO SELECT
PostgreSQL 19 is the most feature-rich SQL release in years — graph queries on your existing tables, less GROUP BY boilerplate, atomic upserts, and temporal DML that actually completes the standard.

Watch on YouTubeUpgrade to PostgreSQL 19: Faster Performance with Zero Config Changes
