[Postgresql 8.2.3] autovacuum starting up even after disabling ?

Hey all,

Iam using PostgreSQL 8.2.3 on RHEL4 (Linux 2.6.20.3-custom #4 SMP x86_64 x86_64
x86_64 GNU/Linux).

I have autovacuum tunrned off in the config, but it still seems to start up once
everyday. What could be the cause of this ?

TIA

$ psql -U postgres
postgres=# show autovacuum;
