TL;DR
A project rewriting Postgres in Rust has achieved a major breakthrough by passing all 100% of the Postgres regression tests. This development could impact database performance and security.
A project rewriting Postgres in Rust has achieved a significant milestone by passing 100% of the Postgres regression tests. This development signals a potential shift in how open-source databases could be built, emphasizing safety and performance. The project aims to create a more reliable and secure version of the popular database system, which is widely used across industries.
The initiative, led by a team of developers and researchers, has successfully rewritten the core components of Postgres in the Rust programming language. Rust’s emphasis on memory safety and concurrency has been a key factor in the project’s approach. According to the project lead, the new implementation has now completed all 2,000+ regression tests used by the official Postgres project, a benchmark for compatibility and stability.
While the original Postgres is written in C, this new version, still in development, aims to demonstrate that a Rust-based database can meet or exceed the reliability standards set by the existing system. The tests cover a wide range of database operations, including transactions, indexing, and data consistency. The project’s team reports that the new implementation not only passes all tests but also shows promising performance improvements in preliminary benchmarks.
Impact of Rust Rewrite on Database Reliability
This milestone suggests that a Rust-based Postgres could offer enhanced safety features, such as reduced risk of memory-related bugs and security vulnerabilities. As Rust is designed to prevent common programming errors, this could lead to more stable database systems. Additionally, passing all regression tests indicates that the new implementation is compatible with existing features and workflows, potentially easing adoption.
For users and organizations relying on Postgres, this development hints at future options for more secure and resilient database infrastructure. It may also influence the broader database ecosystem by encouraging more projects to consider Rust for critical system components.

Background of Postgres in Rust Development
Postgres, originally developed in the 1980s, remains one of the most popular open-source relational databases. Its core is written in C, which has historically been chosen for performance but also introduces risks of memory bugs and vulnerabilities. Over recent years, there has been increasing interest in rewriting parts of critical software in safer languages like Rust.
The project to rewrite Postgres in Rust began as a research effort to explore whether a safer language could maintain or improve performance while enhancing security. Prior to this milestone, the project had successfully implemented core features but had not yet achieved full compatibility with the official regression test suite. Passing all tests marks a key turning point in this ongoing effort.
“Achieving 100% test pass rate confirms that our Rust implementation is on par with the current Postgres in terms of stability and feature support.”

Remaining Challenges and Validation Steps
While passing all regression tests is a significant milestone, it remains unclear how the new implementation will perform under real-world workloads and in production environments. Compatibility with all existing Postgres extensions and tools is still being evaluated, and further benchmarking is needed to confirm performance gains.
Additionally, the project is still in development, and it is not yet clear when or if this Rust-based version will be officially released for general use.
