title: What does the output of \dt mean?
body: <pre><code>postgres=# \c students
  You are now connected to database "students" as user "postgres".
  students=# \dt;
   public | student | table | postgres
  
  students=# \dt+
   public | student | table | postgres | 0 bytes | 
  
  students=# 
  </code></pre>
  
  <p>What does the output of <code>\dt</code> mean? I only only know there is a table <code>student</code> under database <code>students</code> beforehand. </p>
  
  <p>I am using psql (9.6.6).</p>
  
  <p>Thanks.</p>
