H.3. Procedural Languages #
PostgreSQL includes several procedural languages with the base distribution: PL/pgSQL, PL/Tcl, PL/Perl, and PL/Python.
此外，还有一些在 PostgreSQL 核心发行版之外开发和维护的过程语言。 procedural languages的列表在 PostgreSQL wiki 上进行维护。请注意，其中一些项目并未在与 PostgreSQL 相同的许可证下发布。有关每个过程语言的更多信息，包括许可证信息，请参阅其网站和文档。
In addition, there are a number of procedural languages that are developed and maintained outside the core PostgreSQL distribution. A list of procedural languages is maintained on the PostgreSQL wiki. Note that some of these projects are not released under the same license as PostgreSQL. For more information on each procedural language, including licensing information, refer to its website and documentation.
