Yes, currently refcursor based ResultSets fetch all rows at once.  I would
say that this is a missing feature rather than a bug, but in any case it's
something the driver can't do right now.  I'll put this on my todo list, 
but it's not going at the top.

I was under the impression that refcursor returning functions would fade 
with the advent of easier set returning functions.  Have you considered 
using them instead?  The advantage of returning refcursor seems to me that 
you don't need to create a pseudo type for the return value, or deal with 
specifying record types in the query.  Are there other advantages I'm 
missing?
