REASSIGN OWNED: Changes the ownership of database objects owned by a database role.
REASSIGN OWNED BY old_role [, ...] TO new_role
REASSIGN OWNED reassigns all the objects in the current database that are owned by old_row to new_role. Note that it does not change the ownership of the database
old_role:The name of a role. The ownership of all the objects in the current database owned by this role will be reassigned to new_role.
new_role:The name of the role that will be made the new owner of the affected objects.
REASSIGN OWNED is often used to prepare for the removal of one or more roles. Because REASSIGN 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.
The DROP OWNED command is an alternative that drops all the database objects owned by one or more roles.
The REASSIGN OWNED command does not affect the privileges granted to the old roles in objects that are not owned by them. Use DROP OWNED to revoke those privileges.
Reassign any database objects owned by the role named sally and bob to admin;
REASSIGN OWNED BY sally, bob TO admin;
