# PostgreSQL gateway

> Access Cognite Data Fusion (CDF) data via the PostgreSQL protocol.

The PostgreSQL gateway APIs let you query CDF data using standard PostgreSQL tools and SQL. Create gateway users with credentials for PostgreSQL clients, and manage tables that expose CDF resources. Use these APIs to connect BI tools, SQL clients, and applications that use PostgreSQL drivers.
