Thanks for your reply Antoine.

What threw me off was that in the settings.py file  under /usr/lib/esmond/
esmond/settings.py it only specifies the following:

DATABASES = {
    'default': {
        'ENGINE': ESMOND_SETTINGS.sql_db_engine,
        'NAME': ESMOND_SETTINGS.sql_db_name,
        'HOST': ESMOND_SETTINGS.sql_db_host,
        'USER': ESMOND_SETTINGS.sql_db_user,
        'PASSWORD': ESMOND_SETTINGS.sql_db_password,
    }
}

So I was not sure if there would have been some code changes required..

but then again I went deep down into portgres and found that 5432 is just a
default port.. and you can set this to any other number.. so I have set the
postgres to instead use 5431.. then I have used pgbouncer to listen on a vip
to port 5432 so I have solved the problem with loadbalancing postgres. without
having to change anything in the code.

You clustering documentation is right though :) "You are familiar with the
tools or **are willing to learn something new**"

Indeed it was a good challenge to fit all the pieces together.. Normally, I
would never have ventured into postgres/cassandra/apache at all but this
really help me even if I only know the high level how to set it up and get it
running. I have few more tests to be run but for the postgres I am now able to
get it into proper HA with clustering in a 3 node setup.

Thank you again for such an amazing product. I look forward to future
enhancements and help to test these if I can.
