One last thing. This wording has been there since pg10; the only thing
that changed is that it now says "BEFORE ROW triggers" instead of "Row
triggers". I don't think leaving it there one more year is going to get
us too much grief, TBH.
I'm going to leave this as an open item for one or two more weeks and
see if there's more support for Ashutosh's PoV; but if not, my proposal
is to close it without changing anything further.
