What does 'assign a null value to the object' even mean? The concept continues to make no sense. It doesn't "become null" either. You need to learn the basics.

drop_owned

DROP 
OWNED(7)							   SQL Commands 						     DROP OWNED(7)

NAME

       DROP OWNED - remove database objects owned by a database role

SYNOPSIS

       DROP OWNED BY name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  OWNED drops all the objects in 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 will also be revoked.

PARAMETERS

       name   The name of a role whose objects will be dropped, and whose privileges will be revoked.

       CASCADE
	      Automatically drop objects that depend on the affected objects.

       RESTRICT
	      Refuse to drop the objects owned by a role if any other database objects depend on one of the affected objects. This is the default.

NOTES

       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  data-
       base, 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 [reassign_owned(7)] command is an alternative that reassigns the ownership of all the database objects owned by one or
       more roles.

COMPATIBILITY

       The DROP OWNED statement is a PostgreSQL extension.
