Patch by snaga on 2012-10-13 02:22:57 PM: The 2nd patch.
Fixed to support local and global (shared) statistics in the same system view.
Fixed to collect global statistics via pgstat collector process.
Fixed to split PgStat_GlobalStats for different uses, BgWriter stats and LWLock stats.
Patch by snaga on 2012-10-13 02:58:57 PM: Fixed wrong array indexes.
Review by masaofujii on 2012-10-13 06:43:59 PM: The patch causes measurable performance overhead. Needs mechanism to avoid that.
