Default repo. I didn’t add anything when installing Zammad.
pgdg-redhat-all.repo
https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-$releasever-$basearch
Thanks for the tip. I have added a symlink and now the installation went through:
sudo ln -s /usr/pgsql-14/bin/pg_isready /usr/bin/pg_isready
I removed it to avoid potential conflicts
sudo /usr/bin/pg_isready
