Hi, I'm trying to understand the information shown in pg_stat_bgwriter. If I want to identify a possible bottleneck with the bgwriter, for what kind of numbers do I need to watch out? Are the following values OK, or do they indicate that I need to tune my configuration? checkpoints_timed : 6099 checkpoints_req : 291 buffers_checkpoint : 2767641 buffers_clean : 4522 maxwritten_clean : 1 buffers_backend : 609933 buffers_alloc : 1411947 I have read Greg's description (http://www.westnet.com/~gsmith/content/postgresql/chkp-bgw-83.htm), but to be honest I don't understand the explanation. He mentions a "LRU background writer", but I'm not sure to which column that relates. Thanks in advance.
