- appendStringInfo(&buf, _("pages: %u removed,
%u remain, %u skipped due to pins\n"),
+ appendStringInfo(&buf, _("pages: %u removed,
%u remain, %u skipped due to pins, %u skipped frozen\n"),

vacrelstats->pages_removed,
vacrelstats->rel_pages,
-
vacrelstats->pinskipped_pages);
+
vacrelstats->pinskipped_pages,
+
vacrelstats->frozenskipped_pages);

The verbose information about skipping frozen page is emitted by only
autovacuum.
But I think that this information is also helpful for manual vacuum.

Please find attached patch which fixes that.
