Is there a means to set the owner of all objects in a PostgreSQL database at the same time?

The Stack Overflow Q & A Modify OWNER on all tables simultaneously in PostgreSQL describes some nifty ways to change table and other objects to a specific user, and it works swimmingly, however all the suggestions seem to ignore the functions I created. Is there a fairly easy way to reset the owner of ALL objects in the database, including the functions? Doing it by hand is highly undesirable.
