The "software collections" stuff was still in its infancy when I left
Red Hat, so things might've changed, but I'm pretty sure at the time
it was verboten for any mainstream package to depend on an SCL one.
But they very probably wouldn't want postgresql depending on a
compiler package even if the dependency was mainstream, so I rather
doubt that you'll ever see an --enable-jit PG build out of there,
making this most likely moot as far as the official RH package goes.
I don't know what Devrim's opinion might be about PGDG.
