Fwiw what I did for Debian is to require llvm 6.0.1. Older releases
are supported by PG on paper, but effectively at least that version is
needed or else C++ extensions like PostGIS will explode because C++
exceptions aren't handled cleanly.
(The full story is that 5.x is needed for C++ exceptions, and 7 is
needed non-x32 architectures like ppc64(el).)
