PostgreSQL blogs and resources offer developers insights into PostgreSQL database management, administration, and development. Developers can explore tutorials on SQL querying, database design best practices, and advanced PostgreSQL features. Additionally, PostgreSQL resources cover topics such as performance tuning, replication, and high availability setups, providing developers with the knowledge and tools needed to build robust and scalable database solutions.

pgagroal 2.1.0 has been released, bringing new vault security (with migration required), health check functionality, improved failover support, and a Prometheus web console. pgagroal is a high-performance, protocol-native connection pool for PostgreSQL, supporting features like connection limits, prefill, TLS 1.2+, Grafana dashboards, and remote management.

PostgreSQL: pgagroal 2.1

The Prometheus web console is a nice touch—observability being built-in instead of bolted on always makes adoption easier.
Health checks improved failover is where it really starts to feel production-ready at scale. That’s usually where connection poolers get tested the most, not just in steady state but during chaos.
Curious to see how it performs under heavy real-world workloads.
