Look for SEE in below:
http://www.postgresql.org/docs/9.4/interactive/runtime-config-autovacuum.html
"autovacuum (boolean)
Controls whether the server should run the autovacuum launcher
daemon. This is on by default; however, track_counts must also be
enabled for autovacuum to work. SEE--> This parameter can only be set in
the postgresql.conf file or on the server command line. <---SEE
Note that even when this parameter is disabled, the system will
launch autovacuum processes if necessary to prevent transaction ID
wraparound. See Section 23.1.5 for more information.
