pg-gateway

pg-gateway is a TypeScript library that implements the PostgreSQL wire protocol for the server side, enabling developers to build custom Postgres-compatible proxies, middleware, or gateways. The current version is 0.3.0-beta.4, indicating an early beta stage with potential breaking changes. It focuses on low-level protocol handling, differentiating from higher-level clients like node-postgres by giving direct control over the protocol flow. Releases are infrequent and experimental.
