BTW, if your applications happens to be in C++, libpqxx has a class
called CachedResult that would take a lot of this work out of your
hands. It transparently fetches rows on-demand and caches them so
they don't get read more than once. It can also figure out the
size of your result set for you.
You can find libpqxx at http://pqxx.tk/
