PgDog vs. RDS Proxy: Open Source Alternative is 2x Faster
_changxu · x · 2026-09-02
PgDog is an open-source connection pool proxy for PostgreSQL, positioned as a faster alternative to AWS RDS Proxy.
Key Advantages:
- 2x Faster: Benchmarks show better performance than RDS Proxy.
- No Connection Pinning: RDS Proxy pins connections (disabling transaction pooling) when using SET statements, temp tables, or long queries. This can exhaust DB connections at scale. PgDog avoids this, maintaining efficient transaction multiplexing.
- Predictable Autoscaling: Offers more controllable scaling behavior.
While RDS Proxy is managed and easy to deploy, its pinning mechanism can render pooling ineffective under high load, requiring manual query rewrites or connection management.
