DROP_EXTENSION - remove an extension
DROP EXTENSION [ IF EXISTS ] extension_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.
Do not throw an error if the extension does not exist. A notice is
issued in this case.
The name of an installed extension.
Automatically drop objects that depend on the extension.
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.
To remove the extension hstore from the current database:
DROP EXTENSION hstore;
This command will fail if any of hstore's objects are in use in the
database, for example if any tables have columns of the hstore type.
Add the CASCADE option to forcibly remove those dependent objects as
DROP EXTENSION is a PostgreSQL extension.
CREATE EXTENSION (CREATE_EXTENSION(7)), ALTER EXTENSION
