Hi, scanned_tuples variable in LVRelStats is introduced by commit b4b6923e but it seems to me that it's actually not used. We store num_tuples into vacrelstats->scanned_tuples after scanned all blocks, and the comment mentioned that saving it in order to use later but we actually use num_tuples instead of vacrelstats->scanned_tuples from there. I think the since the name of scanned_tuples implies more clearer purpose than num_tuples it's better to use it instead of num_tuples, or we can remove scanned_tuples from LVRelStats.
/* save stats for use later */
vacrelstats->scanned_tuples = num_tuples;
vacrelstats->tuples_deleted = tups_vacuumed;
vacrelstats->new_dead_tuples = nkeep;
Attached small path fixes this.
