Naming the GUC pgstat* seems a little inconsistent. It could be called,
say, track_maintenance_progress_interval/track_vacuum_progress_interval.
That way, it will look similar to existing track_* parameters:

#track_activities = on
#track_counts = on
#track_io_timing = off
#track_functions = none # none, pl, all
#track_activity_query_size = 1024 # (change requires restart)

Also, adding the new GUC to src/backend/utils/misc/postgresql.conf.sample
might be helpful.

Thanks,
Amit
