You can use either dnf or > yum4 on the command line and get the same results. You mentioned you're familiar with Fedora, so you're probably aware of Application Streams -- but for those reading this thread unfamiliar with AppStreams, I'll add the caveat that dnf behaves differently than yum in this regard. Here's some background: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/installing_managing_and_removing_user_space_components/using-appstream_using-appstream Right now, the only EL8 AppStream with multiple versions is postgresql, but it looks like several applications are setup for future multiple streams. To see the AppStream packages, run dnf module list If you squint carefully, you'll see that you can install either PostgreSQL 10 (the default) or 9.6. -- Paul Heinlein heinlein at madboa.com 45°38' N, 122°6' W
