postgresql12 packages missing in RHEL8/CentOS8 repository

A freshly installed repo package doesn't seem to provide all
postgresql12* packages for RHEL8/CentOS8. I've rechecked this on a new
local CentOS 8 VM, downloading 

https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

yields into

# LC_ALL=C dnf search postgresql12

================================================================= Name
Matched: postgresql12
==================================================================
postgresql12-libs.x86_64 : The shared libraries required for any
PostgreSQL clients
postgresql12-odbc.x86_64 : PostgreSQL ODBC driver
postgresql12-devel.x86_64 : PostgreSQL development header files and
libraries
postgresql12-llvmjit.x86_64 : Just-in-time compilation support for
PostgreSQL
postgresql12-plpython.x86_64 : The Python procedural language for
PostgreSQL

And that's it for postgresql12*

So installing postgresql12-server obviously fails:

# LC_ALL=C dnf -y install postgresql12-server

No match for argument: postgresql12-server

The same applies to the other supported major versions. I see the
packages upstream in 

https://download.postgresql.org/pub/repos/yum/12/redhat/rhel-8-x86_64/

so i suppose there is something fishy with the repodata itself.

Thanks,
