Hacker News (Dev, ≥100 P.) · July 9, 2026 curated by Heiko

A Rust reimplementation of PostgreSQL has achieved 100% compatibility with the official Postgres regression test suite. This milestone demonstrates the feasibility of rebuilding a complex database engine in Rust while maintaining complete API and behavioral compatibility with the original C codebase.

The pgrust project, hosted on GitHub by user malisper, has reached a significant technical milestone. The project is a comprehensive reimplementation of the PostgreSQL database engine using the Rust programming language.

According to the project's latest updates, pgrust now passes 100% of the official PostgreSQL regression tests. This achievement confirms that the Rust-based version behaves identically to the original C-based engine across a vast array of complex database scenarios and edge cases.
