Will the absence of LLVM bit-code files effect the functionality of my
"seal_mean_cxx_v2.so" library in Postgresql12 or I just won't benefit from
Postgres JIT compiler (postgresql12-llvmjit package)? The
"seal_mean_cxx_v2.so" was enough to use with Postgres 10.

All the errors occurring for the llvm compilation part relate to the
Microsoft SEAL <https://github.com/microsoft/SEAL> library that my
seal_mean_cxx_v2.cpp uses. Since it is a third party library then maybe I
should post the errors output there and see what they have to say about
it...

Best regerds,
