The ovs-vsctl man page says:

              The  destroy  command  is  only useful for records in the QoS or
              Queue tables.  Records in other tables are automatically deleted
              from   the  database  when  they  become  unreachable  from  the
              Open_vSwitch table.  This means that deleting the last reference
              to  a  record is sufficient for deleting the record itself.  For
              records in these tables, destroy is silently ignored.   See  the
              EXAMPLES section below for more information.
