Hello,
I have found a problem with the following page.
page: https://www.postgresql.org/download/linux/redhat/
I tried install PostgreSQL12 into CentOS 8 as written on this page.
However, I couldn't install it by the following error.
# dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
# dnf install -y postgresql12

No match for argument: postgresql12
Error: Unable to find a match
There is a workaround for this problem.
I executed a below command.
I could install it.
# dnf module disable postgresql
This problem has already reported to Red Hat Bugzilla.
(https://bugzilla.redhat.com/show_bug.cgi?id=1718201#c1)
However, this problem has been already closed.
Because it seems that is not a bug.
Therefore I suggest that add a workaround in this document like an
attachment.
Thanks,
