Re: [Postgres-xc-general] [Postgres-xc-developers] Shell script for simpler Postgres-XC configurati

Hi Suzuki-san,
I looked at the script. It's very well written.

A script inside a contrib module has to be flaxible enough to allow all
kinds of installations of XC. A user may need various combinations of
physical machines, virtual machines and XC components such as coordinator,
datanode and gtm-proxy, standbys for each of these. There can be other
complications like firewalls, VPNs, various network configurations etc.
Every user has his/her own preferences for scripting language. Many
consider bash to be insecure and use c-shell. For those this script won't
be of any use. A script which resides in contrib module has to be flexible
enough to take into consideration all of those combinations and install
components likewise. Writing such a script is a humongous task. So, I don't
think we should add it to contrib module. But, we should add it in our
documentation or provide it on PGXC page.

Same might be the reason, why installers are not part of the code
repository.
