 [Crunchy Data Warehouse](https://www.crunchydata.com/products/warehouse) is a modern data warehouse built on PostgreSQL. Crunchy Data Warehouse extends unmodified PostgreSQL to provide support for fully transactional Iceberg tables and high performance analytics. Crunchy Data Warehouse is available as a managed service on AWS via [Crunchy Bridge](https://www.crunchydata.com/products/crunchy-bridge), fully managed PostgreSQL as a service. Crunchy Data Warehouse can create Iceberg tables directly from a PostgreSQL database or external URLs and can read, query, and update Iceberg tables using PostgreSQL syntax. Using a hybrid query engine that combines PostgreSQL and DuckDB, Crunchy Data Warehouse enables high performance analytical queries of Iceberg tables.
