Well, there are plenty of PostgreSQL modules around these days, and
even if pyPgSQL isn't suitable, I'm sure that there must be one which
can be made to work on Windows and to support server-side cursors. See

Maybe make that (-b / (2. * a)) to avoid getting funny results
when a and b are integers. (Or do a from __future__ import
division, or use Python 3.0, or )
