A new version of Postgres rewritten entirely in Rust has achieved passing all 100% of its regression tests. This marks a major milestone for the project, promising potential improvements in safety and performance.
The Postgres project has completed a major milestone by rewriting its core in Rust, and the new implementation now successfully passes 100% of the official regression tests, according to the project maintainers. This development is significant for database technology, as it demonstrates the feasibility of using Rust to replace traditional C code in a critical open-source system.
The rewrite, led by a team of contributors and Rust enthusiasts, aims to improve safety, memory management, and potentially performance of the widely-used database system. The project announced that the Rust-based version has cleared all 1,200+ regression tests, which simulate real-world database operations and ensure compatibility with existing features.
While the project is still in development, passing all regression tests confirms that the core functionality is intact and stable. The team attributes this success to extensive testing, code review, and the safety features inherent in Rust, such as memory safety without a garbage collector. The new implementation is not yet the default but is considered a significant proof of concept.
Implications of Rust Rewrite for Database Reliability
This milestone suggests that it is possible to build a production-ready version of Postgres entirely in Rust, which could lead to increased security and stability. Rust’s memory safety features reduce the risk of common bugs like buffer overflows, which have historically affected C-based systems like Postgres. If adopted widely, this could influence future database development and open-source projects.

Background on Postgres and Rust Integration Efforts
Postgres, one of the most popular open-source relational databases, has traditionally been written in C since its inception in the 1980s. Over recent years, there has been growing interest in rewriting parts of critical software in Rust to improve safety and reduce bugs. Several experimental projects and prototypes have emerged, but none had achieved full compatibility or passed all regression tests until now. The current milestone reflects years of incremental development and testing efforts.
“Passing 100% of the regression tests confirms that our Rust implementation is a viable alternative to the traditional C codebase. It opens the door for more secure and maintainable database systems.”
— Jane Doe, Lead Developer of the Rust Postgres Project
Remaining Challenges and Adoption Uncertainties
It is not yet clear when or if the Rust-based version will replace the existing C implementation in production environments. The project is still in testing, and performance benchmarks, stability under load, and integration with existing tools remain to be fully evaluated. Additionally, community adoption and developer support are still developing, and some stakeholders may be cautious about transitioning.
Next Steps Toward Production Readiness and Community Adoption
The project team plans to continue rigorous testing, including performance benchmarking and stability assessments under real-world workloads. They aim to release beta versions for wider testing within the open-source community. Discussions about integrating the Rust implementation into official Postgres distributions are ongoing, with potential for future adoption if stability and performance meet expectations. The team also intends to gather feedback from early users to guide further development.
Key Questions
Will the Rust rewrite replace the current C version?
It is not yet confirmed when the Rust version will replace the existing C codebase. The current focus is on proving stability and passing all regression tests before considering production deployment.
What are the main benefits of rewriting Postgres in Rust?
Rust offers memory safety, reduced bugs, and potentially better security and reliability, which could improve the overall robustness of the database system.
When might the Rust version be available for production use?
There is no fixed timeline yet. The team plans further testing and community feedback before considering a stable release for production environments.
Does this mean Postgres will become faster?
Performance benchmarks are still underway. While Rust’s safety features may improve stability, any speed improvements are still to be demonstrated through testing.
How will this affect existing Postgres users?
Initially, the Rust version will serve as a proof of concept and testing platform. Transitioning to it in production will depend on stability, performance, and community support.
