PostgreSQL:作为普通用户运行python存储过程

UPDATE pg_language SET lanpltrusted = true WHERE lanname = 'plpythonu';

不幸的是,我不相信可以运行不受信任的解释程序,除非您的Postgres帐户具有超级用户访问权限。如果您是数据库服务器管理员,CreateUser将询问您新帐户是否应为超级用户。

“untrusted”标志并不意味着运行时不稳定或不可靠,只是它的安全模型不适合存储过程解释器。这可能会导致存储过程中的权限提升,或潜在的灾难性安全错误。

如果您不能以Postgres用户的身份运行或创建超级用户帐户,恐怕您将不得不跳过pl/python,并建议您签出pl/pgsql。 http://www.postgresql.org/docs/8.3/interactive/plpgsql.html

对语言授予[用法]意味着相关用户可以使用该语言创建函数。创建后,必须使用grant execute允许其他用户使用它们。
