这是我建议的架构：

CREATE TABLE Surveys (
    id serial primary key,
    user_email citext,
    survey_data jsonb,
    created_at timestamp default current_timestamp
);
CREATE INDEX surveys_email_idx ON Surveys(user_email);

CREATE USER SurveyWriter;

我知道我需要：

GRANT INSERT ON dbname.Surveys TO SurveyWriter;

但我还需要：

GRANT INSERT, UPDATE ON dbname.surveys_email_idx to SurveyWriter;

还有什么我没有想到的吗？
