Hi, I'm curious -- does "vacuum analyze e.g. table1" improve performance on "insert into table1 ...". I understand the vacuum analyze helps out the query -- select, etc., but just not quite sure on insert. Specifically, I'm doing the following. 1, delete records ... 2, insert records ... if I add "vacuum analyze" in-between this two steps, will it help on the performance on the insert? More importantly, If so, why?
