DROP EXTENSION(7)                 PostgreSQL 14.15 Documentation                DROP EXTENSION(7)

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
       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 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 5.14).

       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.

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.
