+ * rows before vacuuming and the number after vacuuming, rather than just
+ * using the number after vacuuming. This will result in the best average

+ * number of pages in the table stays about the same throughout. (Note that
+ * we do not apply the same logic to VACUUM FULL, because it repacks the table
+ * and thereby boosts the tuple density.)
+ *
+ * An important point is that when the table size has decreased a lot during
+ * vacuuming, the old reltuples count might give an overestimate of the tuple
+ * density. We handle this by scaling down the old reltuples count by the
+ * fraction by which the table has shortened before we merge it with the
+ * new reltuples count. In particular this means that when relpages goes to
+ * zero, reltuples will immediately go to zero as well, causing the planner
+ * to fall back on other estimation procedures as the table grows again.
+ *
+ * Because we do this math independently for the table and the indexes, it's
+ * quite possible to end up with an index's reltuples different from the
+ * table's, which is silly except in the case of partial indexes. We don't
+ * worry too much about that here; the planner contains filtering logic to
