PostgreSQL 中的 DEFAULTS 关键字

顾名思义，在创建表、要素类、栅格数据集以及索引时，默认情况下使用 DEFAULTS 配置关键字下的设置。如果在地理数据库中创建数据时未指定其他关键字，或者指定的关键字缺少某些必要参数，则将使用 DEFAULTS 关键字中的值。

大多数参数在 PostgreSQL dbtune.sde 文件中均会出现两次 - 一次按默认设置出现，另一次以作为注释的参数的形式出现，用以为表空间指派指定正确的语法。这么做的原因是表空间指派的语法会因所创建对象的类型而异。

仅使用参数的一个版本。也就是说，如果想为特定索引指定不同的表空间，则请取消注释该行并注释掉或删除默认的参数。
