If it was me, I'd be putting a 'before' statement level trigger on the
table to raise a warning into the log with the backend pid assuming I
could handle the volume.  There are lots of ways the client could turn
out to be wrong, for example client side connection poolers (which I
tend to hate).  Only when it's 100% proven this is a single backend
case (which none of us really believe is the case including you) is
further research justified.
