RHEL7.4: Failed yum command for PostgreSQL 9.5

Hi all.

While trying to execute yum command for PostgreSQL 9.5 in RHEL 7.4, the command failed with an HTTPS Error 404 - Not
Found. 
Upon accessing the suggested link (https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7.4-x86_64/) from the
browser,the same error was encountered. 
After checking the https://download.postgresql.org/pub/repos/yum/9.5/redhat/, it was confirmed that there was no entry
forrhel-7.4-x86_64, thereby causing yum to fail. 

Aside from rhel-7.4-x86_64, some other versions were also not present. I have summarized them as follows.
9.5
 - rhel-7.0-x86_64
 - rhel-7.4-x86_64
 - rhel-7.5-x86_64

9.6
 - rhel-7.0-x86_64

Would you kindly provide the above versions in the yum repository so that yum will not fail in the future?
Thank you very much.
