insert 'ing a NULL in place of the serial will work too, yes?

INSERT INTO DEVICES (my_serial_id, name, type, ownerteamid) VALUES
(NULL,'scoobydoo', 1, 43);

> One funny thing about serial fields is that you CAN insert a value into
them, but the sequence has no idea what you did, so it will merrily assign
the next value it knows about when you don't provide a value, potentially
causing a conflict.  Therefore, don't do that.  Always let the value be
assigned as above.
