Unable to install pgsql under RHEL8

Hi,

I am not able to install postgresql11 under a fresh RHEL8.

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

They are enabled:

  # yum --quiet repolist pgdg1*
  repo id                  repo name                                 status
  pgdg10                   PostgreSQL 10 8 - x86_64                  239
  pgdg11                   PostgreSQL 11 8 - x86_64                  104

Packages are known by the repository:

  # yum --quiet repoquery --repo pgdg11 postgresql11-server*
  postgresql11-server-0:11.2-2PGDG.rhel8.x86_64
  postgresql11-server-0:11.3-1PGDG.rhel8.x86_64

But they are unknown from local cache:

  # yum search postgresql11-server
  Updating Subscription Management repositories.
  Last metadata expiration check: 0:23:08 ago on Fri May 17 00:23:20 2019.
  No matches found.

If I try to groupinstall:

  # yum groupinstall postgresqldbserver11
  Updating Subscription Management repositories.
  Last metadata expiration check: 0:24:27 ago on Fri May 17 00:23:20 2019.
  No match for group package "postgresql11"
  No match for group package "postgresql11-contrib"
  No match for group package "postgresql11-server"
  Dependencies resolved.

   postgresql11-libs     x86_64     11.3-1PGDG.rhel8      pgdg11     385 k
  [...]

If I yum install using direct URL, it obviously works and pull
postgresql11-libs as dependency:

  # yum install $PGDG_URL/postgresql11-11.3-1PGDG.rhel8.x86_64.rpm
                $PGDG_URL/postgresql11-server-11.3-1PGDG.rhel8.x86_64.rpm


Any clue? Some issue with the provided package list?

Thanks,
