PostgreSQL version: 9.4.4
Operating system: Linux Mint
Description:

Hi,
Installing from the Repository provided here and following all instructions
as for Ubuntu 14.04 (that my Mint 17.02 is based on):
http://www.postgresql.org/download/linux/ubuntu/

After installing all packages, cannot launch postgres:

$ postgres -D /usr/local/pgsql/data
The program 'postgres' is currently not installed. You can install it by
typing:
sudo apt-get install postgres-xc

$ sudo apt-get install postgres-xc
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:

The following packages have unmet dependencies:
postgres-xc : Depends: postgres-xc-client but it is not going to be
installed
E: Unable to correct problems, you have held broken packages.

$ sudo apt-get install postgres-xc-9.4
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package postgres-xc-9.4
E: Couldn't find any package by regex 'postgres-xc-9.4'

I assume I need postgres-xc, but that package is not in your repo, I only
have the one from Ubuntu - for older version of Postgres.

Am I doing something wrong here?
Thanks.
