Parameters
IF EXISTS

in this case.
extension_name
The name of an installed extension.
CASCADE
Automatically drop objects that depend on the extension.
RESTRICT
Refuse to drop the extension if any objects depend on it (other than
its own member objects and other extensions listed in the same
DROP> command). This is the default.
Examples
To remove the extension hstore from the current
database:
DROP EXTENSION hstore;
This command will fail if any of hstore's objects

forcibly remove those dependent objects as well.
