    sequential scan followed by an explicit sort is usually faster than an
    index scan of a large table.
    However, LIMIT combined with ORDER BY often will use an index because
-   only a small portion of the table is returned. In fact, though MAX()
-   and MIN() don't use indexes, it is possible to retrieve such values
-   using an index with ORDER BY and LIMIT:
-    SELECT col
-    FROM tab
-    ORDER BY col [ DESC ]
-    LIMIT 1;
-
+   only a small portion of the table is returned.

    If you believe the optimizer is incorrect in choosing a sequential
    scan, use SET enable_seqscan TO 'off' and run query again to see if an
    index scan is indeed faster.
