Yeah while it's still writing, it's about half as much but most of the
time seems to be in merging etc multiple data sets. I'm wondering
what non-default values you might have set otherwise. Are you running
on SSDs? If so lowering random_page_cost might help, but again, this
might just be a very expensive query as well.
