I just obsoleted this patch.  The new patch should be easier to do
though -- just a one line change I think.

I don't like your wording though; it feels too verbose (and you're
losing the ANALYZE in case it's doing both things).  How about

    snprintf(activity, MAX_AUTOVAC_ACTIV_LEN,
        "autovacuum: VACUUM%s%s", vac
        tab->at_doanalyze ? " ANALYZE" : "",
        tab->at_wraparound ? " (wraparound)" : "");

You're not proposing it for 8.3 right?
