# Postgres Trigger node

Use the Postgres Trigger node to respond to events in [Postgres](https://www.postgresql.org/) and integrate Postgres with other applications. n8n has built-in support responding to insert, update, and delete events.

/// note | Credentials
You can find authentication information for this node [here](/integrations/builtin/credentials/postgres.md).
///

/// note | Examples and templates
For usage examples and templates to help you get started, refer to n8n's [Postgres Trigger integrations](https://n8n.io/integrations/postgres-trigger/) page.

## Events

You can configure how the node listens for events.

* Select **Listen and Create Trigger Rule**, then choose the events to listen for:
	* Insert
	* Update
	* Delete
* Select **Listen to Channel**, then enter a channel name that the node should monitor.

/// note | Postgres event listener and required database permissions
* To listen for trigger events, n8n automatically creates a Postgres trigger on the target table. This trigger is added when you activate a workflow, and removed when you deactivate it.
* If your workflow is inactive, the trigger is also added when you test the workflow and removed once test event listening stops.
* The Postgress trigger calls an automatically-created procedure to tell n8n about the event.
* The user in your Postgres credential must have permissions to create and execute triggers and procedures. In PostgreSQL, this requires superuser access, table ownership, or the TRIGGER privilege - plus CREATE privilege on the schema where the procedure will reside.
