Try to specify the= exact name for the PostgreSQL service, which you can find under the list o= f services, using systemctl.

systemctl list-uni= ts|grep postgresql

Then you can use t= he service or systemctl command.

Better to use pg_c= tl to start/stop PostgreSQL server.

what I did wrong here?  Do I need to add listen_addresses =3D '*' and = port =3D 5432 on both /var/lib/pgsql/data/postgres.conf and /var/lib/pgsql/= 11/data/postgres.conf ?

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 <= br clear=3D"none"> 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 <= br clear=3D"none"> 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 y= ou
need to fix, and local network/systems admins should know enough about
your setup to help a lot faster.
