possibilityof monitoring its activity?

autovacuumor any standard vacuum at all. I couldn't find anything in the docs regarding the specific logging of vacuum
runs.For my nightly vacuum maintenance job, I simply pipe sterr of vacuum verbose analyze to a separate logfile.
Concerningautovacuum, I'd like to have some info on when it runs and which tables it has processed. It is running for
sure,I can often see the autovacuum process pop up in top. I only see no means of finding out what it actually does
whenit's running.
