Sure. In my understanding, unlike tables "free/reusable space" is
actually not reused in index. pgstatindex would be usefull to judge if
REINDEX is needed by showing the growth of physical length and
"free/reusable space".
Maybe "free/reusable space" is not appropriate wording, "dead space"
is better?
