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
Failed to set locale, defaulting to C
PostgreSQL 10 for RHEL/CentOS 8 - x8 100 kB/s | 539 kB 00:05
PostgreSQL 11 for RHEL/CentOS 8 - x8 121 kB/s | 629 kB 00:05
PostgreSQL 12 for RHEL/CentOS 8 - x8 91 kB/s | 471 kB 00:05

PostgreSQL 9.6 for RHEL/CentOS 8 - x 55 kB/s | 518 kB 00:09
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,

Daniel Gustafsson

Seriously speaking, for RHEL 8, we need to add

dnf -qy module disable postgresql

command. Magnus, can you patch this when you can?

Yeah, it seems like it would be better to add this as part of the
instructions rather than as a note on the side.

What is the normal time to do this, in the sequence. After the repository
rpm is installed but before client packages?

And is there any case you'd want to add the pg repositories but *not* do
this? I assume not?
