You did "select count(name)", which counts the number of non-null
occurrences of "name", ie 2. So the loop stops after two iterations,
and never gets to the last row.
I'd lose the count() step entirely and have the loop be driven solely by
the cursor. Actually, why use a cursor at all, as opposed to a FOR IN
SELECT loop?
