It's not always better to squander space: doing so may result in the program not working at all. Squandering time just makes it run slowly. But that's more of a philosophical point.

WRT the update_unless_insrt: there isn't such an option: PrincePawn's referring to the sort of situation where you've got enough information to create a record from scratch, or replace an existing one.

Thus (under Oracle) you get code similar to: 

BEGIN
  INSERT INTO mytab (id, ...) VALUES (id_value, ...);
EXCEPTION
WHEN DUP_VAL THEN
  UPDATE mytab
  SET .. = ...
  WHERE id=id_value;
END;

. id would presumably be limited to the primary key, rather than any unique key. Personally, I think I'd prefer to see it as inserting if the update fails (which avoids the problem of duplicating a different column).
