DROP OWNED — remove database objects owned by a database role
DROP OWNED BY { name | CURRENT_USER | SESSION_USER } [, ...] [ CASCADE | RESTRICT ]   DROP OWNED drops all the objects within the current
   database that are owned by one of the specified roles. Any
   privileges granted to the given roles on objects in the current
   database or on shared objects (databases, tablespaces) will also be
   revoked.
  
nameThe name of a role whose objects will be dropped, and whose privileges will be revoked.
CASCADEAutomatically drop objects that depend on the affected objects, and in turn all objects that depend on those objects (see Section 5.13).
RESTRICTRefuse to drop the objects owned by a role if any other database objects depend on one of the affected objects. This is the default.
   DROP OWNED is often used to prepare for the
   removal of one or more roles. Because DROP OWNED
   only affects the objects in the current database, it is usually
   necessary to execute this command in each database that contains
   objects owned by a role that is to be removed.
  
   Using the CASCADE option might make the command
   recurse to objects owned by other users.
  
   The REASSIGN OWNED command is an alternative that
   reassigns the ownership of all the database objects owned by one or
   more roles.  However, REASSIGN OWNED does not deal with
   privileges for other objects.
  
Databases and tablespaces owned by the role(s) will not be removed.
See Section 21.4 for more discussion.
   The DROP OWNED command is a
   PostgreSQL extension.
