title: "select abc from (select 1) as abc" produces "(1)" instead of "1"
body: <p>In Postgre, why does</p>
  
  <pre><code>select abc from (select 1) as abc
  </code></pre>
  
  <p>produces:</p>
  
  <pre><code>(1)
  </code></pre>
  
  <p>and</p>
  
  <pre><code>select * from (select 1) as abc
  </code></pre>
  
  <p>produces:</p>
  
  <pre><code>1
  </code></pre>
  
  <p>That's really strange to me. Is that the case with MySQL, Oracle, etc?
  I spent hours figuring out why my conditions were failing...</p>
