Pgrust, Postgres in Rust (passing 100% of Postgres regression tests)

In plain words

Pgrust is a PostgreSQL database rewritten in Rust that passes all of PostgreSQL's regression tests and can load existing PostgreSQL data directories. Built for developers interested in exploring an alternative SQL database implementation, it offers a WASM build for quick testing and open-source code for modification. Currently not production-ready and lacking performance optimization and PostgreSQL extension compatibility, it represents early-stage work toward a reimagined database system.

Postgres rewritten in Rust, now faster than Postgres and Clickhouse - malisper/pgrust

In the maker’s words, at launch

pgrust is a PostgreSQL rewrite in Rust I've been working on with my friend Jason. It now passes 100% of PostgreSQL's regression tests and we were even able to boot pgrust off an existing PostgreSQL 18.3 data directory. You can hack on its code or try it out quickly with the WASM build on pgrust.com. It's not…

  PGlite – in-browser WASM Postgres with pgvector and live sync2024 · pglite.dev · ▲509

  Hey, Sam and the team from ElectricSQL here. PGlite is a WASM Postgres build packaged into a TypeScript/JavaScript client library, that enables you to run Postgres in the browser, Node.js and Bun, with no need to install any other dependencies. It's 3mb Gzipped, now has support for many Postgres extensions, including pgvector, and it has a reactive "live query" API. It's also fast, with CRUD style queries executing in under 0.3 ms, and larger, multi-row select queries occurring within a fraction of a single frame. PGlite started as an experimental project we shared on X, and the…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
