Hi Bruce,

This feature has been reverted by a0354e29c41a9fb7491b3c7c23f079b1923c045a.

```
<!--

<listitem>
<para>
Allow the <link linkend="sql-altertable">addition of columns</link> based on domains containing constraints to usually avoid a table rewrite (Jian He)
<ulink url="&commit_baseurl;a0b6ef29a">&sect;</ulink>
</para>

<para>

```

So this item can be removed from the release note.
