Yes, I am. The command line is (in a shell script whom ouput is
redirected in a global file) :

vacuumdb -d $DBNAME -p $DBPORT -U $DBUSR -z -v


That does not explain why we don't get FSM statitics display. The output
ends with:
INFO: vacuuming "public.sometable"
INFO: "sometable": removed 62 row versions in 3 pages
DETAIL: CPU 0.00s/0.00u sec elapsed 0.00 sec.
INFO: "sometable": found 62 removable, 5 nonremovable row versions in 5
pages
DETAIL: 0 dead row versions cannot be removed yet.
There were 534 unused item pointers.
0 pages are entirely empty.
CPU 0.00s/0.00u sec elapsed 0.00 sec.
INFO: analyzing "public.sometable"
INFO: "sometable": scanned 5 of 5 pages, containing 5 live rows and 0
dead rows; 5 rows in sample, 5 estimated total rows
VACUUM

Best regards,

Stéphane
