Certainly easier, but I don't think it'd be better. Matviews really 
aren't the same thing as tables. Off-hand (without reviewing the patch), 
update and delete counts certainly wouldn't make any sense. "Insert" 
counts might, in as much as it's how many rows have been added by 
refreshes. You'd want a refresh count too.
