Based on my extremely naive reading of this code, I have two perhaps equally naive questions: 1. it seems that we will continue to to per-row RI checks for inserts and updates. However, there already exists a bulk check in RI_Initial_Check(). Could we modify this bulk check to do RI checks on a per-statement basis rather than a per-row basis? 2. If #1 is possible, is the overhead of transitions tables too great for the single-row case?
