I'm not sure that I see the point of this at all. ISTM the entire
reason for using a cursor is that you're going to fetch the results
in bite-size pieces. I don't see the current Postgres source code
surviving into the era where >2G rows is considered bite-size ;-)
I thought the int8-LIMIT patch was equally pointless, btw, but at
least it was not very invasive. This one is not passing the minimum
usefulness-to-ugliness ratio for me.
