title: How do I modify this PostgreSQL table?
body: <p>I'm using PostgreSQL in my SBC, running Parabola (Arch and ALARM based). I was reading <a href="https://thejimmyg.github.io/goodingredients/recipe/articles/email3/postfix-gateway.html" rel="nofollow noreferrer">this tutorial</a> so I can use PostgreSQL databases and make Postfix work with them. However, in <a href="https://thejimmyg.github.io/goodingredients/recipe/articles/email3/postfix-gateway.html#the-domain-table" rel="nofollow noreferrer">this step</a> I have to fill up some info in the tables I've created, right? How do I do that? Would be better if I can use pgAdmin3 or phpPgAdmin for this, but if I <strong>have</strong> to do in CLI, there's no problem.</p>
  
  <p>Thanks. </p>
  
  <p><strong>EDIT</strong>: I'm a complete noob with PostgreSQL. I'm trying to learn about it, so if you need more info please tell me how to get it.</p>
