پس مشکلتون از dns نیست ولی عجیبه توی عکس های پست اول ریزالو نتونسته کنه

همونطور که دوستان گفتند آدرس رو کامل وارد کنید

wget   https://download.postgresql.org/pub/repos/yum/12/redhat/rhel-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

اگه بدون مشکل دانلود شد بعدش اینو بزنید

rpm -Uvh pgdg-redhat-repo-latest.noarch.rpm


و اخر

yum install pgadmin4
