Finally, AI won’t replace DBAs, it scales them.
Gülçin's talk at the AI Summit walks through how Xata built the open-source Postgres Agent, powered by LLMs and human-written playbooks.
From pager fatigue to self-healing clusters for a future that’s safer and saner.

Esther Miñano Sanz showing how the CNPG-I Scale-to-Zero plugin lets Postgres hibernate safely and wake up instantly.
Built with CloudNativePG, designed for real-world clusters.
An elegant solution for cost efficiency in ephemeral workloads.

Branch settings, faster.
We reorganized the page and added search.

What changed

Search to jump directly to a setting.
Logical groups with clear labels.
Guardrails to reduce misclicks.

Why it helps

Quicker navigation.
Less guessing, safer edits.

See write latency and replica lag before users do.
New performance charts surface:

WAL sync time → time to flush WAL to disk (disk/flush latency).
Replication lag → how far a standby is behind the primary (freshness).

Want early access? Ping us and we’ll switch it on for your account.

Project-level default database now live in Xata.
Set one default and we point new connection strings, views, and child branches to it by default.
Fewer misroutes and accidental writes to secondary DBs; faster onboarding.
Set it in Project Settings → Default database.
You can override per branch.

Create a Postgres branch in one screen.
Name it → get the branch → run queries.
No org/project setup first.
Sane defaults now, easy rollback later.

Getting paged at 3 a.m + database operations ≠ heroics.

At Berlin Postgres Meetup (Sep 23) we showed our open-source Xata Agent: Autonomously find slow queries, proposes safe fixes, runs on a schedule w/ approvals. As if you have a new database expert colleague.

Recap:

Recap of Berlin Postgres Meetup on September 23rd 2025 by Divyendu Singh

Takeaways from the Sep 23, 2025 Berlin Postgres Meetup: how Xata Agent (open-source Postgres AI agent) helps manage PostgreSQL at scale, Q&A highlights, lessons.

Preload extensions once, use them everywhere.
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.

Thinking about changing your data model?
View your schema as a table or UML diagram.
When you are ready, use xata roll to apply changes without downtime.

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.

Data exploration is easier with the ability to generate SQL from a simple question.
No need to worry about syntax.
Just dive into the data.

Branch metrics provide insight into CPU, memory, throughput, egress, and more.
Use interactive charts to view trends over time or investigate anomalous spikes.
Metrics are stored for up to 60 days at no additional cost.

Have a branch you don’t need running all the time?
Save money by setting scale-to-zero as the default for a project or override it in the branch settings.
