title: What is PostgreSQL equivalent of SYSDATE from Oracle?
body: <p>I want to perform a query using sysdate like:</p>
  
  <pre><code>select up_time from exam where up_time like sysdate
  </code></pre>
  
  <p>which is possible in Oracle.</p>
  
  <p>However, it seems that PostgreSQL doesn't support sysdate. I couldn't find sysdate in postgres documentation. What is the replacement for sysdate in PostgreSQL?</p>
