NAME

       DROP_EXTENSION - remove an extension

SYNOPSIS

       DROP EXTENSION [ IF EXISTS ] 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.

       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 5.13).

       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.
