# Connecting PostgreSQL to Amazon Q Business
<a name="postgresql-connector"></a>

**Note**  
PostgreSQL connector remains fully supported for existing customers through May 31, 2026. While this connector is no longer available for new users, current users can continue to use it without interruption. We are continuously evolving our connector portfolio to offer more scalable and customizable solutions. For future integrations, we recommend exploring the [Amazon Q Business Custom Connector Framework](https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/custom-connector.html), designed to support a broader range of enterprise use cases with enhanced flexibility.

PostgreSQL is an open source database management system. You can connect your PostgreSQL instance to Amazon Q Business—using either the AWS Management Console, CLI, or the [https://docs.aws.amazon.com/amazonq/latest/api-reference/API_CreateDataSource.html](https://docs.aws.amazon.com/amazonq/latest/api-reference/API_CreateDataSource.html) API—and create an Amazon Q web experience.

The Amazon Q PostgreSQL data source connector supports PostgreSQL 9.6.

**Important**  
As a best practice, provide Amazon Q with read-only database credentials. Also, avoid adding tables with sensitive data or personal identifiable information (PII).
