title: values not returned as it should in a SQL query
body: <p>I am running a simple PostgreSQL query on the following table named storelocation2:</p>
  
  <pre><code>store_name   | brand  | city   | store_id
  ----------------------------------------------
  MS Products  | SAMSUNG|Gurugram|5611
  Ajay Electric| SAMSUNG|Gurugram|5611
  Vijay Sales  | SAMSUNG|Gurugram|5611
  </code></pre>
  
  <p>Upon running this command:</p>
  
  <pre><code>postgres=&gt; \d storelocation2;
  </code></pre>
  
  <p>the following table details are returned:</p>
  
  <pre><code>   Column    |         Type          | Modifiers
  -------------+-----------------------+-----------
  store_name   | character varying(20) |
  brand        | character varying(20) |
  city         | character varying(20) |
  store_id     | numeric               |
  </code></pre>
  
  <p><strong>Query</strong>
  Now when I run the select statement:</p>
  
  <pre><code>select city 
  from storelocation2 where 
  brand='SAMSUNG';
  </code></pre>
  
  <p>following results:</p>
  
  <pre class="lang-none prettyprint-override"><code>city
  ------
  (0 rows)
  </code></pre>
  
  <p>which is wrong.</p>
