You can't compute a specific date from that. Nor does it lend itself to combination with other fields to reach a specific date --- adding DD doesn't do it, and if you add MM, you might as well not bother with Q.
I think you very well could if it works e.g. for months: TO_DATE( '2012-4', 'YYYY-MM' ) returns first date of the specified month, so Q could behave similarly.
Anyway, this is obviously not a big issue, just a minor inconvenience ;-)
