+1. There are multiple precedents for that sort of response, which we
introduced exactly so that "SELECT some_function(oid) FROM some_catalog"
wouldn't fail just because one of the rows had gotten deleted by the
time the scan got to it. I don't think it's necessary for the
relation-size functions to be any smarter. Indeed, I'd assumed that's
all that Phil's patch did, since I'd not looked closer till just now.
