We've noticed that the Ubuntu postgresql-12 package has --with-llvm
enabled on x86_64, but not on aarch64. Does anybody know if this was
intentional, or just an oversight?
For what it's worth, it seems the beta postgresql-14 package for Ubuntu
still doesn't have --with-llvm.
I'm not sure if this explains why our aarch64 DBs are missing a
jit_provider GUC variable, but I expect it does explain why
pg_jit_available() tells me no.
