For the record, on Debian unstable:

  Do you want to continue? [Y/n] ^C

I think the addition of LLVM for JIT execution of plans added a lot to the Postgres install baseline (at least in distribution packages, you can compile a much leaner postgres yourself).

Due to the way that the LLVM dependency in postgres works, it could be packaged separately from the base postgres server package. The LLVM interfacing code is runtime loaded, and there's no error if "llvmjit.so" is not on the system, even when the server was built with LLVM support. It's basically a packager's choice whether to do so, or not.
