Auto vacuum

[Carol Walter <walterc@xxxxxxxxxxx>]

I asked questions about auto vacuum earlier.  As I said in my earlier  
email, when I select autovacuum the system responds that it's "on."   
Some here told me when I asked the questions before that I should see  
log entries for it when it "kicks off."  In postgresql.conf, it says  
that the log_destination is 'stderr."  Then it redirects "stderr" to  
a file named 'postgresql -%Y-%m-%d_%H%M%S.log' in a directory called  
pg_log.  I don't see any references to auto-vacuum in the log.  What  
would the references look like?  Is there a parameter I need to set  
in order to make in put auto vacuum entries in the log?   
client_min_messages is set to "notice."  log_min_messages is set to  
"info." log_error_verbosity is set to "default."   
log_min_error_statement is set to "warning."   
log_min_duration_statement is set to 1000

Thanks
