Features (2)
  • PostgreSQL 19 Beta 2 available in RDS Database Preview Environment

    Amazon RDS for PostgreSQL 19 Beta 2 is now available for evaluation, allowing users to test PostgreSQL 19 features on a fully managed database service. Instances in the preview environment are retained for a maximum of 60 days and have specific snapshot usage limitations.

  • Native SQL Property Graph Queries (SQL/PGQ)

    SQL/PGQ enables relationship traversals to be expressed directly within standard SQL, eliminating the need for separate application logic.

Enhancements (3)
  • Parallel autovacuum with configurable worker limits

    PostgreSQL 19 introduces parallel autovacuum with configurable worker limits, designed to prevent routine maintenance from bottlenecking large databases.

  • REPACK CONCURRENTLY for online table rebuilding

    The new REPACK CONCURRENTLY command allows for online table rebuilding and storage reclamation, ensuring production databases remain accessible without relying on third-party extensions.

  • Dynamic logical replication synchronization

    Logical replication now automatically synchronizes sequence values and can be enabled dynamically without a server restart, which helps reduce planned downtime.
