Vacuum only writes normal operations messages to the logs if you have log_min_messages set to DEBUG2 or DEBUG3 (with DEBUG3 giving more output). I'm not sure what query stats are kept for autovacuum activities in 8.3, but in versions <= 8.2.x you can run the following query to see what autovacuum is currently doing:

SELECT current_query
FROM pg_stat_activity
WHERE query_start IS NULL;

This works because autovacuum vacuum queries started by autovacuum apparently don't have their start time (or client_addr) noted.

Hello,

when I put the autovacuum on, where can I check what it does? Is there any log-file?
