I posted once asking about that, but got no responses :)
Here is a vacuum verbose on gborg's database:
INFO: free space map: 1000 relations, 7454 pages stored; 23072 total pages needed
DETAIL: Allocated FSM size: 1000 relations + 20000 pages = 178 kB shared memory.
and this is portal:
INFO: free space map: 1000 relations, 7425 pages stored; 23024 total pages needed
DETAIL: Allocated FSM size: 1000 relations + 20000 pages = 178 kB shared memory.
so, you tell me ... should I increase them? I haven't been able to find
any docs that talk about this :(
