NAME

       DROP_EXTENSION - remove an extension

SYNOPSIS

       DROP EXTENSION [ IF EXISTS ] extension_name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       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.

PARAMETERS

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

COMPATIBILITY

       DROP EXTENSION is a PostgreSQL extension.
