PostgreSQL 19 introduces enhancements like parallel autovacuum with worker limits, an online table rebuild command (REPACK CONCURRENTLY), native SQL property graph queries (SQL/PGQ), and improved logical replication capabilities. Beta 2 includes bug fixes and stability improvements from earlier beta testing.
Users can deploy this pre-release version in a fully managed environment for up to 60 days. Data snapshots are limited to the preview environment, requiring dump-and-load methods for exporting/importing data. The preview offers a risk-managed way to evaluate cutting-edge PostgreSQL advancements before general availability.
