Ok.

I'm a lot less concerned about that, personally. If you're installing
server headers you're already depending on a lot of other libraries, and
you're not that likely to do so on production systems.

Hm, I guess there'd be build failures of extensions if llvm-$ver and
clang aren't installed, because bitcode files will be automatically
built. I don't think there's a dependency on llvm-$ver-dev however?

Sizewise, the bitcode files for postgres and its extensions aren't that
small. ~10MB compressed or such?
