I am just telling you that in your officiall documentation i didn't find that command. I founded oj stack owerflow and when i changed command I succesfully changed owner. Also one more hit: documentation will be much better with examples. I am DBA for a 7 years on ms sql and oracle and they have examples which can make life more easily if you are starting with some new tehnologies like postgres.
Kind regards,
