Not exactly sure of the sequence here, but I think that was before
pg_stat_bgwriter was introduced. That was late in the 8.3 cycle and one
of the primary things I'd like have a good way to reset. I'll dig back to
the commit that wiped out stats_reset_on_server_stat and see what it used
to do. I might suggest something that puts something similar back,
perhaps with a more targeted UI given that pg_stat_reset has taken over
its original primary function.
