错误的坐标表现为缺少相关联的点几何值，触发器过程会悄悄地终止。
Bad coordinates are reflected in the absence of associated point geometry values, and the trigger procedures fail silently.
内部调用（对 ST_Point()）创建一个具有纬度-经度坐标（SRID = 1）的点几何值。
The inner call, to ST_Point(), creates a point geometry with latitude-longitude coordinates (SRID = 1).
当更新源表中的坐标列时，必须构造一个新的点几何值。
When either of the coordinate columns in the source table is updated, a new point geometry must be constructed. The update trigger looks like this
