I think pg_stat_bgwriter is now a misnomer, because it contains the backends' activity. Likewise, pg_stat_walwriter leads to misunderstanding because its information is not limited to WAL writer. How about simply pg_stat_wal? In the future, we may want to include WAL reads in this view, e.g. reading undo logs in zheap. Regards Takayuki Tsunakawa
