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:


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.
