PGNexus Weekly News This Week in PostgreSQL This week covers PostgreSQL 19's SQL/PGQ graph query rewrite mechanism, a major connection pooler release with Odyssey 1.5.1, a practical Aurora index rebuild strategy using Blue/Green Deployments, and powa-archivist 5.2.0 adding PostgreSQL 19 support. Together these highlight new query capabilities, tooling updates, operational performance techniques, and monitoring improvements relevant to PostgreSQL users across development and production environments.
