Yep, that's a cross-compiler, hence "x86_amd64". As I said, it doesn't
actually matter very much on an x64 host as the target arch binaries run
fine on the host arch. The only reason you'd need the native 64-bit
compiler is if you're compiling huge programs that cause the 32-bit to
64-bit cross-compiler to run out of memory. Not an issue for Pg.
