pgx is a PostgreSQL driver and toolkit for Go.
The tool addresses the need for efficient, feature-rich PostgreSQL connectivity in Go applications. It provides a pure Go driver that exposes PostgreSQL-specific capabilities like LISTEN/NOTIFY and COPY protocol support, which are unavailable through the standard database/sql interface. Beyond the driver itself, pgx includes a toolkit of underlying packages for parsing the wire protocol and mapping types between PostgreSQL and Go, enabling developers to build alternative drivers, proxies, load balancers, and logical replication clients. The driver supports approximately seventy PostgreSQL types, automatic statement preparation and caching, batch queries, binary format support for custom types, connection pooling, and full TLS control.
Developers should choose pgx when their application targets PostgreSQL exclusively and no other libraries requiring database/sql are in use, as the pgx interface delivers higher performance than the standard interface. The tool suits projects that need PostgreSQL-specific features or require maximum query performance. For applications requiring database portability or integration with libraries expecting database/sql, the project provides a stdlib adapter that wraps pgx for standard interface compatibility, and connections can be converted between the two interfaces as needed.
The project maintains active engagement with issues and pull requests, demonstrating responsiveness to user needs. Development follows a structured approach with clear contribution guidelines documented in CONTRIBUTING.md. The codebase receives regular updates addressing bug fixes and feature enhancements. The project provides comprehensive documentation including API references, a getting started guide, and architectural resources such as a detailed presentation on pgx design.
