this is the dev, not live. but this is after it gets done with that table:
CPU 0.00s/0.00u sec elapsed 0.00 sec.
INFO: analyzing "public.fastadder_fastadderstatus"
INFO: "fastadder_fastadderstatus": scanned 2492 of 2492 pages, containing
154378 live rows and 0 dead rows; 30000 rows in sample, 154378 estimated
total rows
and there's nothing at the end of the whole vacuum output about pages
actual command:
vacuumdb -U postgres -W -v -z djns4 &> vacuum.log
I tried it with all databases too
?
thanks
