Well, there is pg_proboscis that py-postgresql was based on.
It is quite lacking by comparison, but functional.

But no, I don't plan to backport it.

It shouldn't be loading it all into memory by default... If it is,  
it's a bug.
However, It should be grabbing some pretty big chunks when it needs  
more data to supply a fetchXXX request, so if you're looking at a wide  
result set, that could use a large amount of memory.
