```
$ sudo -u postgres psql
postgres=# \c students
You are now connected to database "students" as user "postgres".
students=# create table student(name char(30), gender char(30), birthday date)
students-# \dt
No relations found.
students-# insert into student value ('Tom', 'male', '11-21-2000')
students-# \dt
No relations found.

```

I was wondering why `\dt` doesn't show any table under database `students`, even after I create a new table `student` and after I insert a record into the table?

Thanks.
