Thanks for sending a patch.

+    /* autovacuum cannot be anti-wraparound and not aggressive vacuum */
+    Assert(aggressive);
+    msgfmt = _("automatic aggressive vacuum to prevent wraparound of table \"%s.%s.%s\": index scans: %d\n");

While adding this comment in lazy_vacuum_rel() is adapted, I think that
we ought to make the assertion check more aggressive by not having it
depend on if log_min_duration is set or not.  So why not moving that to
a place a bit higher, where aggressive gets defined?
