Today we're open sourcing the Xata platform, a cloud-native Postgres platform. - Fast copy-on-write branching. - Automatic scale-to-zero. - 100% Vanilla Postgres. We run upstream Postgres, no modifications. - Production grade: HA, failover/switchover, upgrades, PITR, IP filtering, etc.

Xata is now open source. Apache 2.0. Postgres platform with Copy-on-write branching at the storage layer. Copy a TB-sized database in seconds. Inactive copies scale to zero automatically. 100% vanilla Postgres.

Batching is often used to process large volumes of data but a batch size that works in one network setup can perform poorly in another. We applied automatic batch size tuning to Postgres snapshots in pgstream to adapt across different network environments. Check the post 👇 xata.io/blog/postgre...

Postgres constraints are the rules that keep your data clean. Types tell you *what* can be stored but constraints enforce *what must be true*. If a row violates a rule, Postgres rejects it. No silent corruption. A few well-chosen constraints prevent entire classes of bugs. xata.io/blog/constra...

We explored giving AI agents access to compute (via Sandbox) and database via Xata branches and some “commandments” to follow a developer-like workflow.

Can an AI Agent follow the same workflow that human developers can? We explored giving AI agent access to the database branch, a compute sandbox to execute code and instructions to follow a developer workflow (in plain English) and the experiment was a success.

Club Xata Rome 2025: our biannual reset. We traded Zoom for a shared table and left with sharper plans + stronger bonds.

PostgreSQL 18 is here 🎉 🐘 • Async I/O (io_uring/worker), faster reads • More index hits (skip scan, OR) • uuidv7(), virtual generated cols • OAuth2; Ask for Xata access and try PostgreSQL 18.

The summer edition of the London Postgres Meetup is behind us! Thanks to the organisers for a great evening. Chris Ellis gave a sharp talk on UUIDs, and Andrew Farries introduced pgroll, our open-source tool for zero-downtime schema changes. Always a joy to talk Postgres over pints!

I wrote a longish blog post: xata.io/blog/are-ai-... After vibe coding, can we talk about vibe observability?

pgroll looks amazing — it orchestrates the underlying (sorta tedious) mechanics of the expand-contract pattern for zero-downtime, hot-swap migrations in Postgres. github.com/xataio/pgroll

Here is a quick demo of the Xata Agent, which we released this week as open source: github.com/xataio/agent It is an AI Agent that monitors your PostgreSQL instances, tunes your config, and helps you optimize your queries.

Yesterday we published our open-source Xata agent to help everyone get better at managing their Postgres databases. Let me know what you think! And @simonwillison.net has already tried it and shared his feedback 👇🏽

Announcing the Xata Agent: github.com/xataio/agent It's an open-source AI agent that helps you with Postgres operations. You give it access to logs, metrics, and SQL access and it helps you tune your db and troubleshoot issues.

Leveling up! Sleek new web app for the Postgres Compatibility Index is live. Big thanks to Contributors: @gunnarmorling.dev , @tudor.golubenco.org , Frank Pachot, Deepak Mahto , Matt Cornillon and Akash. Postgres.Is 🚀✨ 🐘 Blog => tinyurl.com/3wr3vy5x

I sometimes use Cursor AI to format my SQL :)

Not all operations require the same level of locking, and PostgreSQL offers tools and techniques to minimize locking impact. If you'd like to learn more about this, check out my follow-up blog here: pgroll.com/blog/anatomy...

If you are in Berlin, there's a new "All in Kubernetes" meetup: lu.ma/302v7ag3?tk=... I'm plannig to go and mingle :)

Ahoj friends 👋 If you’re interested in Postgres, we’re (xata.io) giving free tickets to upcoming Prague PostgreSQL Developer Days, p2d2.cz. I will be also giving a talk so if you decide to come, say hi! Email us at [email protected]. See you in Prague on the 29th of Jan! #p2d2 #postgres #prague

AI-assisted technical content is an interesting topic. There’s a lot of stigma at the moment (see some of the comments) but to me I’d rather have Armin’s knowledge with the help of AI than not at all.

Learned to do latte tulips this weekend. This is my third attempt. An ok start?

Dear @Netflix.bsky.social Please consider making Bucha movie available in more countries.It’s a very important film that everybody should see Friends,please help share this post to show that the interest in the movie is high Thank for supporting Ukrainian filmmakers& important stories,Netflix!

Congrats @prequel-dev.bsky.social!

Just realized the .cooking TLD is a fun one for dev environments. Like yourcompany.cooking

I'm doing a tricky operation with @pulumi.com, so I'm double checking all my flags, and this one made me smile: -e, --emoji Enable emojis in the output

Nice to see the new pgroll.com website on HN 🎉

pgroll gets its own website 🎉 pgroll.com The organic traction of pgroll has been great, so we're going to invest more into it. Open-source zero-downtime, reversible, schema changes for PostgreSQL.

🚀 Postgres Compatibility Index (PCI): Think your shiny new Postgres derivative is "Postgres-compatible"? Test it, score it, and know the truth. 🐘 Thanks @gunnarmorling.dev @tudor.golubenco.org @benesch.bsky.social @deverts.bsky.social for the inspiration. Blog ==> tinyurl.com/mmfcbczz

I'm low-key excited and genuinely curious about how successful Aurora DSQL will be. The architecture (see @marcbrooker.bsky.social 's excellent blog posts) has several neat ideas for distributing OLTP. On the other hand, people want Postgres and this is (for now) not really Postgres.
