I tried both and none of them work.
Finally, I made it work.
1. commented all of the module and none being used /etc/pam.d/postgres
2. added extra 32 after address of pg_hba.conf
3. I stop and start postgres as root fine without error.
thank you for all your helps.
Now I need to learn/play how to create a new postgres DB
have a wonderful days.

You have to run postgres services with postgres user.

sorry I was out yesterday.
I stop the services and kill -9 all the postgresql process and run ps aux|grep postgres. Nothing is running and start the service as 'service posgresql
start" I still get eh error
'Job for postgresql.service failed because the control process existed with error code. See "systemctl status posgresql.service" and "journalctl

As the systemctl status posgresql.service I get

Try to specify the exact name for the PostgreSQL service, which you can find under the list of services, using systemctl.
systemctl list-units|grep postgresql
Then you can use the service or systemctl command.
Or
Better to use pg_ctl to start/stop PostgreSQL server.

Some of them will be from the stock Red Hat repositories, and some will
be from the PGDG repository. I haven't used that repository, and I
haven't done much on an RPM-based system for a while so I can't give you
any more specific information.
It's possible - but very tedious and difficult - to install a package
with a large dependency tree entirely by hand. I *have* done this
myself in the past, and I recall a few cases where it literally took two
or three hours to get everything installed to support the specific
package I started out trying to install. This is why tools like yum
were developed; they do the work of checking through the list to see
what's required, and where it can be installed from.
This isn't specific to Postgres; it's how the underlying OS package
system works. You may want to see if someone in your office has more
experience installing packages on RHEL with yum and ask them to give you
a hand. You've got several issues around yum's basic operation that you
need to fix, and local network/systems admins should know enough about
your setup to help a lot faster.
