I have some thoughts about your descriptions in the docs (V34). It looks clearer now, but in seems to me it still contains some inaccuracy.. 1. Naming: The meaning of 'visible/frozen_pages_cleared' seems to me as cleared pages rather then cleared marks... Maybe it should be 'visible_page_marks_cleared'? 2. Mention of a VACUUM in the docs may be understood as related to manual VACUUM command only. However, autovacuum is accounted as well.. I think we can use just term 'vacuum' here as a facility rather than command. -- regards, Andrei Zubkov Postgres Professional
