How to sync live postgres data with your AI

Connect your database once. From then on, your AI agent sees every change the moment it hits your Postgres instance.

Short answer

How do I keep my AI updated with live Postgres changes?

ElectricSQL streams changes from your Postgres database directly to your AI agent. This keeps your agent's context perfectly aligned with your live data without manual refreshes. You'll see how the sync engine handles the heavy lifting below.

Where the data goes.

Real-time data outcomes.

Once the sync is active, your agent gains immediate awareness of your database state.

LIVE

Instant context updates

The AI sees new rows or updated values immediately. It can respond to data changes without you asking it to re-scan the table.

SYNCED

Consistent state

Your agent's knowledge stays in lockstep with your Postgres instance. It prevents the hallucinations that happen when an AI works with old data.

ACTION

Triggered responses

Because the data is live, your agent can react to specific database events. It knows when a status changes or a new record arrives.

HUMAN

Manual oversight

The AI observes the data but doesn't change your database structure. You remain in control of the actual Postgres schema and write operations.

The workflow

What your AI does when data changes.

The sync engine handles the data movement so your agent can focus on the logic.

  1. Capture changes

    The engine watches your Postgres WAL to catch every insert, update, and delete. It turns these database events into a stream.

    get_shape

  2. Map the schema

    The agent uses the current database structure to understand how to interpret the incoming stream. It learns the table shapes automatically.

    get_shape

  3. Update context

    The new data is fed into the agent's active window. This ensures the next prompt you send uses the most recent information.

    get_shape

  4. Notify user

    If the data change requires a decision, the agent flags the update. It presents the new information for your review.

FAQ

How the sync behaves.

  • 01

    Can the AI change my Postgres data?

    No. This connector is for reading and syncing data to the AI. It does not have tools to write, delete, or modify your database.

  • 02

    Does this work with any Postgres database?

    Yes, as long as your instance supports logical replication for the sync engine to capture changes.

  • 03

    Will the AI delete my tables?

    No. The AI only has read access to the data stream provided by the sync engine.

  • 04

    How much data can it sync?

    The sync engine handles the stream, but the amount of data your AI can actually 'remember' depends on your AI client's context window.

  • 05

    Is the data sync real-time?

    Yes. It uses streaming to push changes to the agent as they occur in the database.
