Lean Postgres binary protocol proxying strips a connection down to essentials. Instead of translating queries into text or adding layers of interpretation, it passes raw binary messages straight between client and server. This means lower latency, fewer CPU spikes, and predictable performance under load.
The Postgres binary protocol is already efficient. A lean proxy keeps it that way by avoiding features that bloat the data path—like query rewriting, buffering, or verbose logging in the hot loop. It tracks connections, routes packets, and leaves the rest untouched. The result: throughput close to a direct connection, but with the flexibility of routing, observability, connection pooling, or sharding when needed.
In high-concurrency systems, every microsecond counts. Lean proxying ensures that protocol messages—startup, bind, execute, sync—make the trip with minimal handling. By operating at the frame level, such a proxy maintains full compatibility with Postgres client libraries while keeping overhead near zero.
