So you're worried about the wrong thing entirely. The query is taking
less than 3 seconds, which may be reasonable considering it's producing
111000 join rows. The big problem is the other 630 seconds, which is
evidently update overhead. I'm wondering if you have any triggers or
foreign keys leading to or from this table.
