Yeah, this is one of the issues that I've been trying to solve in the
last 2 days.
RHEL 8.3 again broke LLVM, upgraded from 9 to 10. The problem is
CentOS, which is still 8.2 and ships LLVM 9.
If I build packages on RHEL, it breaks CentOS. If I build on CentOS, it
breaks Red Hat.
As an interim solution, I spinned another build VM, which runs CentOS
8.2 and pushed those packages to 8.2 directory.
So, if you edit your repo config file, and replace $releasever with
8.2, if will work *for now*, until CentOS releases 8.3, then you can
revert that change.
Alternatively remove llvmjit package until CentOS 8.3 is out.
I am trying to rebuild LLVM 10 and push to our repos. This is not the
best solution, but at least it will be useful if Postgres is the only
thing installed on the OS.
Let me know if you think of another solution.
