WarehousePG ships with a large set of modules and supports additional separately installed packages. They fall into four categories:
- Bundled modules ship with WarehousePG and don't require a separate package install. See the reference page for the full list and WHPG 6.x/7.x compatibility.
- Additional extensions are packages that require a separate install on each host before you can enable them. See the reference page for the full list and WHPG 6/7.3/7.4/7.5 compatibility.
- Procedural languages extend WarehousePG with additional programming languages for writing functions and stored procedures.
- External components are separately installed tools that integrate with WarehousePG but aren't database extensions.
