Hm, you're right; I was looking at the logic in the triggers themselves
(in ri_triggers.c).
So the next question is, what pg version is the original poster using?
because 8.1.x doesn't report trigger execution times, and 8.2.x would use
a single bitmap index scan with an = ANY condition, not a BitmapOr.
