Commit 960869da08 (database statistics) conflicted with this. Rebased.
I'm concerned about the behavior that pgstat_update_connstats calls
GetCurrentTimestamp() every time stats update happens (with intervals
of 10s-60s in this patch). But I didn't change that design since that
happens with about 0.5s intervals in master and the rate is largely
reduced in this patch, to make this patch simpler.
regards.
