ALTER TABLESPACE ... MOVE ... OWNED BY

Browse Source 
Add the ability to specify the objects to move by who those objects are
owned by (as relowner) and change ALL to mean ALL objects.  This
makes the command always operate against a well-defined set of objects
and not have the objects-to-be-moved based on the role of the user
running the command.

Per discussion with Simon and Tom.

by the user will be moved. Note that the superuser is considered an owner
