No it doesn't; it's a loop, and your patch will change nothing. Your
original version tried to stop after fetching one tuple, which was
wrong because of visibility considerations.
Now that I think about it, this code could do a two-key scan backwards
and stop after finding the first (last) valid tuple, but that's more
than a one-line change.
