Using 8.3.1 No matter what I try I've never seen any evidence that autovacuum runs on my system. I set autovacuum_vacuum_threshold = 50 Then run a process to do updates on a table, shouldn't autovacuum kick in after 50 updates?
Nope, it also depends on the number of rows of your table and on the configuration of the autovacuum_vacuum_scale_factor parameter.
You should also configure log_autovacuum_min_duration to 0 to see the autovacuum operations.
