Hello, It seems theses pages are not up to date :https://www.postgresql.org/download/linux/debian/ - Debian supported stable versions are wheezy, jessie, stretch.https://www.postgresql.org/download/linux/ubuntu/ - Ubuntu supported LTS versions are 14.04 (trusty), 16.04 (xenial), 17.04 (zesty).
Both : Add ppc64el architectures I suggest use 9.6 instead of 9.4.
