Unable to init and run postgresql-12 on centos 8.2.2004

Hello,

I'm trying to install postgresql 12 on CentOS 8.2 as following -

First I run docker container on the host -
# docker run --privileged -dit --name pgdg centos:8.2.2004 /sbin/init

Then inside the container, I run the commands given below -

# yum -y install glibc-langpack-en glibc-locale-source
# localedef -i en_US -f UTF-8 en_US.UTF-8

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

# dnf -qy module disable postgresql

# dnf install postgresql12-server

# /usr/pgsql-12/bin/postgresql-12-setup initdb

# systemctl enable postgresql-12

# systemctl start postgresql-12

Postgresql starts at this point...

However, when I try to stop it, it just hangs -

# systemctl stop postgresql-12 (hangs)

Can someone help how to resolve this?

Thanks,
Vishal
