New description:
Add new methods in the classic module, similar to getresult(),
dictresult() and namedresult(), but returning iterators of rows instead of
lists of rows.
Or instead of adding new methods, add a boolean flag to the existing
methods (see also #23).
One problem here is that PQExec always reads the whole result into memory
anyway, so using it would thwart the idea of saving memory by using an
iterator. We probably need to create a cursor behind the scenes for this
to make sense.
See also #67 (add methods for returning scalar values) in this context.
