Greets, I just noticed something odd: I'm busy with a manual vacuum on a table and an autovacuum keeps firing up as well. Thinking this looks rather weird, I pg_cancel_backend() the autovacuum process: current_query | vacuum analyze page_citation_text; age | 11:34:10.759279 ... current_query | autovacuum: VACUUM ANALYZE public.page_citation_text age | 11:33:15.824014 However, Pg keeps firing up the autovacuum: current_query | vacuum analyze page_citation_text; age | 11:46:57.245568 ... current_query | autovacuum: VACUUM ANALYZE public.page_citation_text age | 00:11:50.571 It seems counter-intuitive to have two vacuum procs running on the same table... how is this possible? I'm trying to vacuum the table as quickly as possible so a manual vacuum seems to be in order as my understanding (and experience) is that the autovac is a hell of a lot slower to mitigate impact on general performance. Anyway, is that autovac duplicating work or locked out and waiting?
