Don't think I believe that those are the same query --- there's a
CTE in the second one that doesn't appear in the first, and it is
eating a lot of time too.
I have a vague recollection that there are cases where optimizations
are possible in plain SELECT but not in data-modifying queries.
So maybe this isn't pilot error but something triggered by that.
We'd need to see a self-contained test case to verify that though.
