Answer 1

You need to connect the repository from PostgreSQL itself .
To do this, add to /etc/apt/sources.list.d/pgdg.list:
Import signed repository key:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Further:

sudo apt-get update
sudo apt-get install postgresql-9.4 postgresql-client-9.4
