Issue in postgresql installation - Target version Postgresql 14.

Dear team,

We are facing issues during installation of postgresql at our environment.

This command completed with no errors.....

dnf install -y
https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Then we ran this command....

dnf install postgresql14-server-14.5-1PGDG.rhel8.x86_64.rpm
postgresql14-14.5-1PGDG.rhel8.x86_64.rpm
postgresql14-libs-14.5-1PGDG.rhel8.x86_64.rpm

and got the following messages

Error:
Problem 1: cannot install the best candidate for the job
- nothing provides lz4 needed by postgresql14-14.5-1PGDG.rhel8.x86_64
Problem 2: package postgresql14-server-14.5-1PGDG.rhel8.x86_64 requires
postgresql14(x86-64) = 14.5-1PGDG.rhel8, but none of the providers can be
installed
- cannot install the best candidate for the job
- nothing provides lz4 needed by postgresql14-14.5-1PGDG.rhel8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to
use not only best candidate packages)
*Again tried `dnf update` and `dnf install -y postgresql14-server` , but
still stuck with below error:*

# dnf update
