Assicurati di aver installato tutti i pacchetti correttamente e di aver aggiornato le sezioni del repository yum [base] e [updates] prima dell'installazione come indicato nella guida
. Abbiamo CentOS 7 con PostgreSQL 9.5 e funziona perfettamente con i seguenti passaggi:
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
e infine, systemctl status postgresql-9.5.service dovrebbe mostrarti qualcosa del genere:
postgresql-9.5.service - PostgreSQL 9.5 database server
