llvm-toolset is needed by postgresql11-devel and postgresql12-devel in this
setup it seems, but why do you need those? If what you want is Postgis,
then the postgis RPM should be enough and that shouldn't need devel
packages at all, and therefore not the llvm packages.

If you do actually need the devel packages, you need to enable the scl
repo. On centos, that means install centos-release-scl. On RHEL, I believe
you do "yum-config-manager --enable rhel-server-rhscl-7-rpms".
But again,if "all" you want is PostGIS, they shouldn't be needed.
