Removes an extension from a Greenplum database.
DROP EXTENSION [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DROP EXTENSION removes extensions from the database. Dropping an extension causes its component objects to be dropped as well.
You must own the extension to use DROP EXTENSION.
This command fails if any of the extension objects are in use in the database. For example, if a table is defined with columns of the extension type. Add the CASCADE option to forcibly remove those dependent objects.
- IF EXISTS
Do not throw an error if the extension does not exist. A notice is issued.
The name of an installed extension.
Automatically drop objects that depend on the extension, and in turn all objects that depend on those objects. See the PostgreSQL information about Dependency Tracking.
Refuse to drop an extension if any objects depend on it, other than the extension member objects. This is the default.
DROP EXTENSION is a Greenplum Database extension.
