   Mathesar – open-source collaborative UI for Postgres databases▲281

   Hi HN! We just released the public alpha version of Mathesar (https://mathesar.org/, code: https://github.com/centerofci/mathesar). Mathesar is an open source tool that provides a spreadsheet-like interface to a PostgreSQL database. I was originally inspired by wanting to build something like Dabble DB. I was in awe of their user experience for working with relational data. There’s plenty of “relational spreadsheet” software out there, but I haven’t been able to find anything with a comparable UX since Twitter shut Dabble DB down. We're a non-profit…

   PgQueuer – Transform PostgreSQL into a Job Queue▲376

   PgQueuer is a Python job queue that uses PostgreSQL for everything — queue storage, locking, notifications. No Redis, no RabbitMQ, no separate broker to operate. If your app already has Postgres, you already have the broker. After ~2 years and 26 minor releases, 1.0 ships today as the first stable release. Strict semver from here on. Thanks to everyone who contributed and left feedback!

    pgxman – npm for Postgres extensions▲81

    pgxman is npm for Postgres extensions, simplifying the discovery and use of extensions so you can easily enhance your applications. Installing and updating Postgres extensions is an uphill battle. You're left searching for the right build tools and grappling with often unclear and incomplete compiling instructions to even try one out. But with pgxman, we've streamlined the process to one simple step: pgxman install [extension name]. For example, to build parquet_s3_fdw manually, you'd need to: 1. Download the parquet_s3_fdw source code; 2. Figure out how to build it by looking at README.…

    Hi HN, Been hacking on a simple way to run agents entirely inside of a Postgres database, "an agent per row". Things you could build with this: * Your own agent orchestrator * A personal assistant with time travel * (more things I can't think of yet) Not quite there yet but thought I'd share it in its current state.

    SnapQL – Desktop app to query Postgres with AI▲104

    SnapQL is an open-source desktop app (built with Electron) that lets you query your Postgres database using natural language. It’s schema-aware, so you don’t need to copy-paste your schema or write complex SQL by hand. Everything runs locally — your OpenAI API key, your data, and your queries — so it's secure and private. Just connect your DB, describe what you want, and SnapQL writes and runs the SQL for you.
