title: regarding backslash from postgresql
body: <p>i have a noob question.</p>
  
  <p>I have a record in a table that looks like '\1abc'</p>
  
  <p>I then use this string as a regex replacement in <code>re.sub("([0-9])",thereplacement,"2")</code></p>
  
  <p>I'm a little confused with the backslashes. The string i got back was <code>"\\1abc"</code></p>
