Rust never sleeps, comments never chill
pgrust passes 100% of the Postgres regression tests
Rusty Postgres just aced the big test, and the crowd is already fighting about what that means
TLDR: pgrust, a Rust rewrite of the Postgres database, just passed all the main official tests, a big sign it closely matches the original’s behavior. The community reaction was classic chaos: some cheered the milestone, while others questioned the rewrite itself and warned that add-on support is the real make-or-break issue.
A tiny programming miracle just dropped, and the internet immediately turned it into a food fight. pgrust, a rewrite of the popular database Postgres in the Rust programming language, has now passed 100% of Postgres’s official regression tests and the extra isolation tests too. In plain English: it behaves like the original in a long list of important checks, can even start from an existing Postgres data folder, and is suddenly looking a lot less like a toy project and a lot more like a serious experiment. The catch? Its own creators are waving a giant caution sign: not ready for production, not speed-tuned, and not yet friendly with existing add-ons.
But the real entertainment is in the comments, where the vibe swings from impressed to exhausted. One camp basically said, “Cool achievement, but why rewrite it at all?” One commenter questioned whether Rust really makes internal changes easier, asking why, if artificial intelligence is so helpful, developers wouldn’t just use it on the old C code directly. Another went even spicier, declaring Rust brings more mental overhead than C, which is the kind of statement guaranteed to summon a 400-reply flame war. And then came the drama queen energy: “Again pgrust? This is going to look like The Revenge of Zealots,” a line that practically begs to be printed on a meme.
Still, amid the snark, there was one grounded reality check: passing tests is huge, but add-on support is where the real trust battle begins. Translation: the crowd sees the milestone, but they’re not handing over the keys just yet.
Key Points
- •pgrust is a Rust rewrite of PostgreSQL being developed by the author and Jason Seibel.
- •The project targets compatibility with Postgres 18.3 and passes PostgreSQL regression and isolation tests.
- •pgrust is disk compatible with Postgres and can boot from an existing Postgres 18.3 data directory.
- •The article states that pgrust is not production-ready, not performance optimized, and not compatible with existing Postgres extensions.
- •The project’s stated goal is to make Postgres easier to modify internally while preserving PostgreSQL behavior and using AI-assisted programming to explore deeper server changes.
