title: How to avoid the idle connections in postgres 9.3
body: <p>We are using postgres 9.3 version. And we are getting connections like "set extra_float_digits =3" as idle minimum 40 connections . I'm surprised even though I disabled that parameter in conf file still getting too many connections.</p>
  
  <p>Can anyone suggest me to avoid those connections in postgres 9.3 without using pgbouncer.</p>
