DROP EXTENSION(7) PostgreSQL 14.19 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.
