如何只安装Postgresql client（以9.4 为例）

　

　Install the repository RPM:

yum install https://download.postgresql.org/pub/repos/yum/9.4/redhat/rhel-7-x86_64/pgdg-redhat94-9.4-3.noarch.rpm

Install the client packages:

yum install postgresql94

1. Optionally install the server packages:

   yum install postgresql94-server

2. Optionally initialize the database and enable automatic start:

   /usr/pgsql-9.4/bin/postgresql94-setup initdb
   systemctl enable postgresql-9.4
   systemctl start postgresql-9.4
