I've mentioned that in my first email, and put in details:
- pgstat_report_bgwriter() is called once, by the bgwriter.
- pgstat_report_checkpointer() is called three time, all by the
checkpointer.
- pgstat_report_archiver() is called twice, all by pgarch.c.
So all of them don't have a problem, two calls cannot happen
concurrently.
