Yeah, maybe.  Certainly ri_triggers is putting a huge amount of effort
into working around the SPI/parser/planner layer, to not a lot of gain.

However, it's not clear to me that that line of thought will work well
for the statement-level-trigger approach.  In that case you might be
dealing with enough tuples to make a different plan advisable.
