PostgreSQL用户的存储过程名称

Question

I was wondering if there was a way to detect the log in name of the user executing the query which triggers a stored procedure? Say, I have a trigger on table_a that fires when a particular column is changed. I would like to retrieve the name of the logged in user who executed the query which triggered the stored procedure running.

Is this possible?

事实证明，有一个公认的关键字current_user可以执行我想要的确切操作-保留执行查询的当前用户的用户名。
