The patch looks good to me. I have some comments:
The description of pg_stat_reset_shared() should mention
pg_stat_walwriter in the document.
We should implment something like pg_stat_reset_shared('all') so that
we can easily reset
all cluster-wide statistics counters to zero?
Some background workers may write WAL because WAL buffer is full. So you seem to
need to change those processes so that they also can increase the
xlog_dirty_writes
counter.
