IIRC It was possible to determine how long a _certain_ query took in 7.0.x.

Ok, I found the statistics flags too, but how am I to tell which stats 
go to which query ?

I think that having backend pid in QUERY STATISTICS should be enough to 
help out.

I can't even figure this out by time elapsed, as I don't know when the 
stats were written
