8.8.几何类型

Geometric data types represent two-dimensional spatial objects. Table 8.20 shows the geometric types available in PostgreSQL.

几何数据类型表示二维空间对象。表8.20显示了PostgreSQL中可用的几何类型。

A rich set of functions and operators is available to perform various geometric operations such as scaling, translation, rotation, and determining intersections. They are explained in Section 9.11.

一组丰富的函数和运算符可用于执行各种几何运算，例如缩放，平移，旋转和确定相交。在第9.11节中对它们进行了说明。
