CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
create DOMAIN Rating SMALLINT CHECK (VALUE>0 AND VALUE<=5);
create TYPE Feedback(
student_id uuid ,
rating Rating,
feedback TEXT
);

它给我这个错误

ERROR:  syntax error at or near "uuid"
LINE 4: student_id uuid ,
                   ^
SQL state: 42601
Character: 138

我使用pgadmin4和UUID数据类型在创建表时工作正常，但在创建类型时出错。
