——row955至971，调整英文和中文内容为：
      A partition must have the same column names and types as the partitioned
      table to which it belongs. Modifications to the column names or types of
      a partitioned table will automatically propagate to all partitions.
      <literal>CHECK</literal> constraints will be inherited automatically by
      every partition, but an individual partition may specify additional
      <literal>CHECK</literal> constraints; additional constraints with the
      same name and condition as in the parent will be merged with the parent
      constraint.  Defaults may be specified separately for each partition.
      But note that a partition's default value is not applied when inserting
      a tuple through a partitioned table.

      分区必须与其所属的分区表的字段名和类型相同。
      对分区表字段名或类型的修改，将自动传播到所有分区。
      <literal>CHECK</literal>约束将自动被每一个分区继承，但是单独的分区可以指定额外的<literal>CHECK</literal>约束；与父表相同名称和条件的额外约束将被父表约束合并。

     我们不推荐在新应用中使用 OID：在可能要用到的地方，使用一个标识列或者其他序列生成器作为表的主键会更好。不过，如果你的应用确实需要用到 OID 来标识一个表的特定行，我们推荐在表的<structfield>oid</structfield>列上创建一个唯一约束，来确保表中的 OID 在计数器回卷后能唯一标识行。如果你需要一个数据库范围的唯一标识符，要避免假定 OID 在表之间也是唯一的，应该用<structfield>tableoid</structfield>和行 OID 的组合来实现该目的。

<!--==========================orignal english content==========================
     <para>
      The use of <literal>OIDS=FALSE</literal> is not recommended
      for tables with no primary key, since without either an OID or a
      unique data key, it is difficult to identify specific rows.

      我们不推荐对没有主键的表使用<literal>OIDS=FALSE</literal>，因为没有 OID 或 唯一数据键，就很难标识特定的行。
