DROP EXTENSION(7) PostgreSQL 9.6.6 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 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,
"Dependency Tracking", in the documentation).
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.
