53.63. pg_ts_template #
pg_ts_template 目录中包含定义文本搜索模板的条目。模板是文本搜索词典类别的实现骨架。由于模板必须由 C 语言级别的函数实现，因此创建新模板仅限于数据库超级用户。
The pg_ts_template catalog contains entries defining text search templates. A template is the implementation skeleton for a class of text search dictionaries. Since a template must be implemented by C-language-level functions, creation of new templates is restricted to database superusers.
PostgreSQL 的文本搜索功能在 Chapter 12 中有详细的描述。
PostgreSQL’s text search features are described at length in Chapter 12.
