I can explain my motivation by suggesting this update.
pg_stat_io is a very impressive feature. So I decided to try it.
I see 4 rows for some 'standalone backend' out of 30 total rows of the
view.
The attempt to find description of 'standalone backend' in the docs
did not result in anything. pg_stat_io page references pg_stat_activity
for backend types. But pg_stat_activity page doesn't say anything
about 'standalone backend'.
I think this question will be popular without clarifying in docs.
