Patch by snaga on 2012-07-08 02:56:49 PM: Initial version.
Review by jjanes on 2012-08-11 10:13:27 PM: Needs documentation.
Probably needs function to show reset time.
Is it OK for counts not to survive a restart?
Patch by snaga on 2012-09-25 06:44:09 PM: Revised to use the stat collector process instead of writing shared memory directly. So, the statistics could be kept on restart, and could be reset by pg_stat_reset_shared('walwriter').
