46. PL/Python - Python Procedural Language
To install PL/Python in a particular database, use
CREATE EXTENSION plpython3u.如果將語言安裝到 template1 中，則所有隨後建立的資料庫將自動安裝該語言。
PL/Python is only available as an “untrusted” language, meaning it does not offer any way of restricting what users can do in it and is therefore named
plpython3u. A trusted variant plpython might become available in the future if a secure execution mechanism is developed in Python. The writer of a function in untrusted PL/Python must take care that the function cannot be used to do anything unwanted, since it will be able to do anything that could be done by a user logged in as the database administrator. Only superusers can create functions in untrusted languages such as plpython3u.自行編譯原始碼的使用者必須在安裝程序中特別啟用 PL/Python 的編譯。（更多相關資訊，請參閱安裝說明。）使用預先編譯版本的使用者可以在單獨的套件中找到 PL/Python。
