The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/runtime-config-resource.html Description:
hi, i am not sure if definition of vacuum_cost_page_miss paraemter on https://www.postgresql.org/docs/current/runtime-config-resource.html is correct. The current definition states: "vacuum_cost_page_miss (integer) The estimated cost for vacuuming a buffer that has to be read from disk. This represents the effort to lock the buffer pool, lookup the shared hash table, read the desired block in from the disk and scan its content. The default value is 10." Shouldn't it be more like: "The estimated cost for vacuuming a buffer that has to be read from outside of shared buffer cache" (including both disk and OS cache?)
