Hi. While I read the documentation I found the following description about some columns in pg_stat_bgwriter.
https://www.postgresql.org/docs/devel/static/monitoring-stats.html#pg-stat-bgwriter-view This table shows cluster-global values, not per-backend values. > maxwritten_clean: > Number of times the background writer stopped a cleaning scan > because it had written too many buffers > buffers_backend: > Number of buffers written directly by a backend > buffers_backend_fsync: > Number of times a backend had to execute its own fsync call > (normally the background writer handles those even when the > backend does its own write) Since the values are the summary in a cluster, the 'a backend's in the last two seems wrong *to me*. I suppose the 'a backend' should be just 'backends' or 'backends other than the background writer' (This seems a bit verbose.). regards, -- Kyotaro Horiguchi NTT Open Source Software Centerhas -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
