DROP EXTENSION(7) PostgreSQL 18.6 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 member objects, and other explicitly dependent routines (see AL- TER ROUTINE (ALTER_ROUTINE(7)), the DEPENDS ON EXTENSION extension_name ac- tion), 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 is- sued 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 5.15). RESTRICT This option prevents the specified extensions from being dropped if other objects, besides these extensions, their members, and their ex- plicitly 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 data- base, 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.
