No, i don't have autovacum.
We tried it sometime ago, and the applications began to take "time-out".
I think we don't need autovacum, along the day the application don't get slow, sometimes is faster (maybe the use of the applications is less).
The actual machine is Dual Core Xeon 1.5 and 2 Gb RAM.

Have you tuned autovacuum?  Maybe you need it to be more frequent on
certain tables or something.
