I manually* download the relevant files from
https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-8-x86_64
and https://download.postgresql.org/pub/repos/yum/15/redhatrhel-8-x86_64 to
my laptop, then use WinSCP to copy them to my firewall-restricted Linux
servers. Then "yum install". Works like a charm.

Yes, I had to manually determine the package names, but that was a one-time
process. Now, I just update the version numbers in my Windows shell script.

*technically, with a PowerShell script.
