Hello, It seems the new VACUUM VERBOSE output is not quite as helpful as 8.0. In 8.0 I get a nice output at the end like this: INFO: free space map: 1377 relations, 22478 pages stored; 44112 total pages needed DETAIL: Allocated FSM size: 100000 relations + 2000000 pages = 17702 kB shared memory. Which tells me exactly what I need to do with max_fsm_pages/relations. The new output appears: booktown=# VACUUM FULL VERBOSE books ; INFO: vacuuming "public.books" INFO: "books": found 32804 removable, 14 nonremovable row versions in 242 pages DETAIL: 0 dead row versions cannot be removed yet. Nonremovable row versions range from 48 to 72 bytes long. There were 0 unused item pointers. Total free space (including removable row versions) is 1845484 bytes. 241 pages are or will become empty, including 241 at the end of the table. 1 pages containing 6768 free bytes are potential move destinations. I am sure the above tells me the same thing but not as easily. Comments? Sincerely, Joshua D.
