I would add something like:

"The insert, update and delete tuple counts from partitions are
propagated to their parent tables, so autovacuum knows to process them
too."

Because I spent a considerable amount of time on this patch, I think
it's fair to list me as co-author, after Hosoya-san's name.  Same with
the PQtrace() item.

Thanks
