Hi all,
I sometimes set autovacuum_vacuum_scale factor = 0 but only when I also
set autovacuum_vacuum_threshold to some non-zero number to force vacuums
after a certain number of rows are updated. It takes the math out of it
by setting the threshold explicitly.
But in this case he has also set autovacuum_vacuum_threshold to only
25! So I think you have to fix your settings by increasing one or both
accordingly.
Regards,
Michael Vitale
