Re: auto_explain contrib moudle

Ok, I'm looking at the direction of ExecutorStart/End hooks...

I think instr_time is enough here,
but why do you think Instrumentation is needed?

There might be another approach to have a stopwatch stack in
the contrib module instead of the core. I think it is cleaner
because it works even if multiple modules use the stopwatch
at the same time. Am I missing something?
