I have a second look at this issue and now I think the fix in v1 patch
is correct.  I think the comment needs to be updated for this change,
maybe something like


I've updated the comment based on your suggestion. Please look at the patch
attached.


Could you please confirm the issue, Richard's and my conclusions, and the
correctness of the patch, in light of the upcoming May releases?
Maybe I'm wrong, but I think that this bug can lead to data corruption in
databases where BRU triggers are used.

If the defect is real, but the patch proposed is not good enough, I would
register it on the commitfest to continue working on it.

Best regards,
Alexander
