You must own the extension to useDROP EXTENSION.
Parameters

nameThe name of an installed extension.
CASCADEAutomatically drop objects that depend on the extension, and in turn all objects that depend on those objects (seeSection 5.14).
RESTRICTRefuse to drop the extension if any objects depend on it (other than its own member objects and other extensions listed in the same
