Manage the PostgreSQL Connector

The Composer PostgreSQL connector lets you access the data available in the PostgreSQL query engine using the Composer client. The Composer PostgreSQL connector supports PostgreSQL versions 9.4 through 12.1.

Before you can establish a connection from Composer to PostgreSQL storage, a connector server needs to be installed and configured. See Manage Connectors and Connector Servers for general instructions and Connect to PostgreSQL for details specific to the PostgreSQL connector.

After the connector has been set up, you can create data source configurations that specify the necessary connection information and identify the data you want to use. See Manage Data Source Configurations for more information. After data sources are configured, they can be used to create dashboards and visuals from your data. See Create Dashboards.
