Logging autovacuum activity

[Ireneusz Pluta <ipluta@xxxxx>]

Hello,

How can I make sure that autovacuum is running, beyond believing that all autovacuum_ settings in 
postgresql.conf are set correctly?

In the 8.1 I could see:
LOG:  autovacuum: processing database "test"
in the log.

But I can't find it in the 8.2.4.

I could see some developers discussions about making changes to logging autovacuum activity, however 
could not track the discussion tight enough to find what the final solution is.

Thanks
