It does not show it. I run freebsd, does it matter?

Anyway, I found that I may enable logging autovacuum messages by setting:

  log_min_messages = debug1

in postgresql.conf

I found it from postgresql-8.2.4/src/backend/postmaster/autovacuum.c, where I read in line 420:

         ereport(DEBUG1,
                 (errmsg("autovacuum: processing database \"%s\"", db->name)));

and this is what the developers were discussing and I did not understand initially.

Sorry for the noise.
