DROP_EXTENSION - remove an extension
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.
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 well.
DROP EXTENSION is a PostgreSQL extension.
