pgrx is a framework for developing PostgreSQL extensions in Rust.
The framework addresses the challenge of building PostgreSQL extensions, which traditionally requires writing C code and navigating PostgreSQL's complex internal APIs. pgrx provides Rust bindings to PostgreSQL's extension interface, allowing developers to write extensions in Rust while maintaining safety guarantees that the language provides. The tool handles the low-level details of interfacing with PostgreSQL, abstracting away much of the complexity involved in extension development.
Developers should choose pgrx if they want to build PostgreSQL extensions but prefer working in Rust rather than C. The framework is suitable for projects that need custom PostgreSQL functionality and benefit from Rust's memory safety and type system. The tool supports a wide range of PostgreSQL versions, from version 13 through version 18, plus version 19beta1, making it viable for extensions targeting multiple PostgreSQL releases.
The project maintains active development with regular testing infrastructure and documentation. The team actively engages with the community through Discord and accepts financial sponsorship to support ongoing work.
