DROP_EXTENSION - remove an extension

DROPEXTENSION is a PostgreSQL extension.

DROPEXTENSION removes extensions from the database. Dropping an extension causes its member objects, and
       other explicitly dependent routines (see ALTER ROUTINE (ALTER_ROUTINE(7)), the DEPENDS ON EXTENSION
       extension_name action), to be dropped as well.

       You must own the extension to use DROPEXTENSION.

       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.

       IF EXISTS
           Do not throw an error if the extension does not exist. A notice is issued in this case.

       name
           The name of an installed extension.

       CASCADE
           Automatically drop objects that depend on the extension, and in turn all objects that depend on those
           objects (see Section 5.15).

       RESTRICT
           This option prevents the specified extensions from being dropped if other objects, besides these
           extensions, their members, and their explicitly dependent routines, depend on them. This is the
           default.

       CREATE EXTENSION (CREATE_EXTENSION(7)), ALTER EXTENSION (ALTER_EXTENSION(7))
