en: PostGIS has begun a transition from the existing naming convention to an SQL-MM-centric convention. As a result, most of the functions that you know and love have been renamed using the standard spatial type (ST) prefix. Previous functions are still available, though are not listed in this document where updated functions are equivalent. The non ST_ functions not listed in this documentation are deprecated and will be removed in a future release so STOP USING THEM.
zh_Hans: PostGIS 已经开始从现有的命名约定过渡到以 SQL-MM 为中心的约定。 因此，您所了解和喜爱的大多数函数都已使用标准空间类型 (ST) 前缀进行了重命名。 以前的功能仍然可用，但本文档中未列出更新后的功能等效的功能。 本文档中未列出的非 ST_ 函数已被弃用，并将在未来版本中删除，因此请停止使用它们。
