[Postgres-xc-general] Postgres '-X' invalid option

[Matteo D. <M.D...@gs...>]

Hi all.

I am testing Postgres XC for a project I am starting at my work place .
I apologize
if the following is already a known issue.

I was following the installation tutorial on the Postgres XC web site
(on Sourceforge)
and I have managed to install Postgresql XC 1.0.1 on a Debian Wheezy VM
(creating a
deb package from the sources), but when I am trying to start the
postgres instances
(using the postgres user) for the datanodes I'll get this error:

postgres: invalid option -- 'X'

I was looking under postgresql-xc-1.0.1/src/backend/tcop/postgres.c and
in fact this option
is not listed on the function process_postgres_switches(...), nor it is
mentioned in main.c,
located under postgresql-xc-1.0.1/src/backend/main.
I also tried to find this option on the main Postgresql versions
(9.1/9.0/8.4) but it seems that
there isn't any reference to a '-X' option.

According to the short tutorial on
http://postgres-xc.sourceforge.net/docs/1_0/install-short.html
this is the required procedure to start the cluster. If I try to start
the datanodes without the '-X'
option I'll get another error:

Postgres-XC: must start as either a Coordinator (--datanode) or Data
Node (--datanode)

which means, I guess, that this option has something to do with the
roles of the instances.


Thanks in advance.


Best regards,
Matteo
