    Description copied from class: PermissionsDescriptor
    
    This method checks if the passed authorization id is same as the owner of the object on which this permission is defined. This method gets called by create view/constraint/trigger to see if this permission needs to be saved in dependency system for the view/constraint/trigger. If the same user is the owner of the the object being accessed and the newly created object, then no need to keep this privilege dependency
    
    Specified by:
    
    checkOwner in class PermissionsDescriptor
    
    Returns:
    
    boolean If passed authorization id is owner of the table
    
    Throws:
