<span class="original">
The catalog <structname>pg_description</structname> stores optional descriptions
(comments) for each database object. Descriptions can be manipulated
with the <link linkend="sql-comment"><command>COMMENT</command></link> command and viewed with
<application>psql</application>'s <literal>\d</literal> commands.
Descriptions of many built-in system objects are provided in the initial
contents of <structname>pg_description</structname>.
</span>
各データベースオブジェクトに対して付けられたオプションの補足説明（コメント）は<code class="structname">pg_description</code>カタログに格納されます。
補足説明は<a class="link" href="sql-comment.html" title="COMMENT"><code class="command">COMMENT</code></a>コマンドで編集でき、<span class="application">psql</span>の<code class="literal">\d</code>コマンドで表示できます。
多くの組み込み型のシステムオブジェクトの説明は、<code class="structname">pg_description</code>の最初の部分で提供されています。

See also <link linkend="catalog-pg-shdescription"><structname>pg_shdescription</structname></link>,

are shared across a database cluster.

<a class="link" href="catalog-pg-shdescription.html" title="52.49. pg_shdescription"><code class="structname">pg_shdescription</code></a>も参照してください。
こちらは、データベースクラスタに渡って共有されるオブジェクトに関する説明について、同様の機能を行います。
