I have to really agree with you. I really appreicate your time for
responding this. I am getting better knowledge on the bucardo and also on
postgres with all your support.

I will take your suggestions. I will put the
check_postgres.pl--action=bloatin our nagios and monitor it and take
necessary actions

again thanks for the help
