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

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

Ok, thank you Michael. Using the '--cordinator' and '--datanode' options
I was able to start my test cluster and now it's up and running :-).

May I also suggest a slightly modification on
src/backend/postmaster/postmaster.c?
At line 780, inside the #ifdef PGXC ... #endif the line

write_stderr("%s: Postgres-XC: must start as either a Coordinator
(--datanode) or Data Node (--datanode)\n" (...)

should be something like this:

write_stderr("%s: Postgres-XC: must start as either a Coordinator
(--coordinator) or Data Node (--datanode)\n" (...)

Is it right?

Best regards,
Matteo
