I think result sets the correct term since the Append node is combining partial
results made by other parallel nodes. Doing some reading it seems to me that
"results sets" isn't incorrect (though I might have misunderstood the grammar
from not being a native speaker), but I'm still inclined to change since we
consistently use "result sets" in the rest of the documentation.
