Should I set the max_fsm_pages to the value reported (vacuum
verbose) as pages stored or the value reported as total pages needed? I
ran full + analyze vacuums in my database (vacuumdb –f –z –v <database
name>) a couple of times and I got the following reports: INFO: free space map: 454 relations,
22274 pages stored; 147328 total pages needed DETAIL: Allocated FSM size: 1000
relations + 20000 pages = 178 kB shared memory And INFO: free space map: 454 relations,
22242 pages stored; 147328 total pages needed DETAIL: Allocated FSM size: 1000
relations + 20000 pages = 178 kB shared memory I am not sure if I need to raise the
max_fsm_pages to something larger than 22242 (e.g. 40000) or larger than
147,328. |
