Postgres Rewritten in Rust Passes All Regression Tests for Version 18.3
Key points
- pgrust matches output of Postgres 18.3 across 46,000 tests
- Not production-ready; performance optimization pending
- Multithreaded internals and built-in connection pooling introduced
Overview of pgrust
pgrust is a complete rewrite of the Postgres database in Rust. It is designed to match the expected outputs of Postgres version 18.3, successfully passing all 46,000 regression tests. With disk compatibility, it can boot from existing Postgres 18.3 data directories.
Goals and Features
The primary goal of pgrust is to simplify internal changes to Postgres while preserving its behavior. Features include multithreaded internals, built-in connection pooling, and improved support for JSON workloads. Additional experiments are ongoing to explore storage methodologies, including designs that eliminate the need for vacuuming.
Current Limitations
As of now, pgrust is not production-ready, lacking performance optimization and full compatibility with existing Postgres extensions. While certain contrib modules have been ported, many procedural language extensions like PL/Python and PL/Perl do not yet work.
Testing and Installation
Users can access a WebAssembly demo at pgrust.com. Installation instructions are available for various operating systems including Docker, macOS, and Debian/Ubuntu, with specific commands provided for running and building the software.
