Re: autovacuum log?

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.
