CentOS: Postgres 11 yum repo missing repomd.xml (Errno 14 404 Not Found)

I'm trying to install Postgres 11 on an EC2 CentOS 7 server but can't get past the Postgres yum repo. I try to install the repo:
yum install https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm
and get [Errno 14] HTTPS Error 404 - Not Found for the URL https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-2-x86_64/repodata/repomd.xml.
The error is correct - that URL does NOT exist. rhel-2* doesn't exist in https://download.postgresql.org/pub/repos/yum/11/redhat/. How can I work around what appears to be a yum definition bug? Is there a more valid mirror somewhere?
I was having the same problem on Amazon Linux 2.
This worked for me:
sudo rpm -Uvh https://yum.postgresql.org/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm
sudo sed -i "s/rhel-\$releasever-\$basearch/rhel-7.5-x86_64/g" "/etc/yum.repos.d/pgdg-11-centos.repo"
sudo yum install postgresql11
Found the correct 2nd statement here:

How can install sensu-plugins through a proxy or by offline package

I was trying to install PostgreSQL-9.3 and postgis-2.1 using this command
sudo apt-get install postgresql postgresql-contrib postgis postgresql-9.3-postgis-2.1
I got this error
The PostgreSQL server failed to start. Please check the log output:

2016-03-18 10:54:56 IST DETAIL: File must be owned by the database user or root, must have no write permission for "group", and must have no permissions for "other".
I searched for the error and got some solutions from the below links
PostgreSQL won't start: "server.key" has group or world access
I tried the solution but this gave me error permission denied..
and the second one I tried was
chmod 640 /etc/ssl/private/ssl-cert-snakeoil.key
this gave error operation not permitted. Please help me with this..
