-      The toast_tuple_target specifies the minimum tuple length required before
-      we try to move long column values into TOAST tables, and is also the
-      target length we try to reduce the length below once toasting begins.
-      This only affects columns marked as either External or Extended
-      and applies only to new tuples - there is no effect on existing rows.
-      By default this parameter is set to allow at least 4 tuples per block,
-      which with the default blocksize will be 2040 bytes. Valid values are
-      between 128 bytes and the (blocksize - header), by default 8160 bytes.
-      Changing this value may not be useful for very short or very long rows.
-      Note that the default setting is often close to optimal, and
-      it is possible that setting this parameter could have negative
-      effects in some cases.

+      can result in unusual amounts of free space being left in pages which
+      can be too small to accommodate any new tuples.
       This parameter cannot be set for TOAST tables.
