Уверете се, че сте инсталирали всички пакети правилно и сте актуализирали секциите на хранилището на yum [base] и [updates] преди инсталиране, както е споменато в ръководство
. Имаме CentOS 7 с PostgreSQL 9.5 и работи перфектно със следните стъпки:
vi /etc/yum.repos.d/CentOS-Base.repo
yum localinstall http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm
yum list postgres*
yum install -y postgresql95-server.x86_64 postgresql95-contrib.x86_64 postgresql95-libs.x86_64
/usr/pgsql-9.5/bin/postgresql95-setup initdb
systemctl enable postgresql-9.5.service
systemctl start postgresql-9.5.service
и накрая, systemctl status postgresql-9.5.service трябва да ви покаже нещо подобно:
