I realize I didn't really answer the question.

The use case is when you're UPDATEing or DELETEing a row and you want to 
quickly assert that there should be exactly one row.  For example, if 
you've previously locked a row with SELECT .. FOR UPDATE, and now you 
want to UPDATE or DELETE it, it better be there (or you have a bug 
somewhere).
