Thus, an update of a row always creates all-new index entries for the row, even if - the key values did not change. (HOT tuples are an exception to this + the key values did not change. (<link linkend="storage-hot">HOT + tuples</link> are an exception to this statement; but indexes do not deal with those, either.) Index entries for dead tuples are reclaimed (by vacuuming) when the dead tuples themselves are reclaimed. |
