Checking the code, 8.1.x does report trigger times, so AndrewSN is
mistaken on that point.

However, it's also the case that 8.1 does have the suppress-the-trigger
logic for FKs, and it works fine for me in a simple test.  I'm using
8.1 branch tip, but there are no relevant changes since 8.1.0 as far
as I can see in the CVS logs.

What is that non-FK trigger shown in your results?

Could it possibly be firing an extra update on the table?
