OK, I did a little research on this.  It turns out that this code in
vacuum.c:

    if (vacstmt->verbose)
        MESSAGE_LEVEL = NOTICE;
    else
        MESSAGE_LEVEL = DEBUG;

controls whether the message comes out as a NOTICE or a DEBUG.  My guess
is that you are doing a VACUUM VERBOSE, and those are coming out in the
server logs.

Guys, is this the proper way to handle this?
