Attnum == 0 is invalid and doesn't belong to either user columns or system columns. You're actually right that it's in limbo, but I believe the change you suggested actually makes the correct comment incorrect. In the condition you're asking about, I don't think we really need to worry about an impossible case. If I wanted to pay more attenstion to it, I would use an assertion, but I don't think it's necessary here. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
