fail to install postgresql15 on Alma9 - Mailing list pgsql-general

Hello,

I am foillowing instructions on

https://www.postgresql.org/download/linux/redhat/

I select version "15"
I select "Red Hat Enterprise, Rocky, AlmaLinux or or Oracle 9"

I get this command to run:

"dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm"

But then I fail to install postgersql15:

# yum install postgresql15-server
Last metadata expiration check: 0:22:07 ago on Tue 18 Jun 2024 12:16:52 PM CDT.
No match for argument: postgresql15-server
Error: Unable to find a match: postgresql15-server

I can install postgresql16-server sussessfully but not 15.
I need 15. What am I doing wrong?

Thank you,
Dmitry
