The pg_maintenance scripts check the state of the autovacuuum flag in the
postgres config files. If it is enabled they simply quit and don't do
anything. Disabling autovacuum causes them to run... So you can leave them
uncommented...
Although why it causes the "Incomplete start-up packet" messages is a
mystery...
