<p class="MsoPlainText">> And the connection are getting rejected.<o:p></o:p></p>
<p class="MsoPlainText">> Is it an issue from pgpool2 end..or is it a connection issue as we are trying to make connection from the windows environment in order to test the load balancing through PGPOOL2.<o:p></o:p></p>
