Xata: Postgres with data branching and PII anonymization | xata
Relaunching Xata as "Postgres at scale". A Postgres platform with Copy-on-Write branching, data masking, and separation of storage from compute.
xata.io
📣 We have a brand new Postgres platform with:
Instant Copy-on-Write branching
Built-in data anonymization
Separation of storage and compute
100% vanilla Postgres
It’s for staging/dev environments as well as for production workloads.

Giving agents access to realistic data via branches should scale the feature development without increasing costs.
This shows how you can use the “scale to zero” feature of the Xata platform to improve feature development while keeping costs in check.

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.

What you should know about constraints in PostgreSQL | xata.io by Gulcin Yildirim Jelinek
In this blog, we explore Postgres constraints through the pg_constraint catalog, covering table vs. column constraints, constraint triggers, domains and more.

AI agents are “clever” to use available tools like grep, sed to find the relevant code files based on a prompt.
Here we experiment with giving AI agent tools to change environment variables in a repository that it checked out and it worked.

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

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.

Set shared_preload_libraries at the branch level and every database on that branch shares the same foundation. Example:
pg_stat_statements, pg_trgm → consistent query stats + text ops across envs.
Notes: applies to all DBs on the branch.

PostgreSQL 18 is supported on Xata.
Try PG18 in a safe, branch-based workflow:
How to start:
• Clone with anonymization → test on look-alike data.
• Create a PG18 branch → run queries and migrations.
• When ready, promote with pgroll for zero-downtime changes.

Shipping Text to SQL you can trust isn’t just prompting.
It’s engineering for simplicity.
At Xata we use a tiny context, pass schema + current SQL, a focused system prompt, and the right model per task.
Fewer moving parts, cleaner UX.
