If only Travis supported more arches like arm64v8 to help test this in a sane way. 😇

I guess we could fake out the case statement to test building on amd64 too.

LOL the image is slightly smaller when we build the .deb files ourselves (~266 MB vs ~260 MB); that's encouraging. Probably some minor update to some build-dep and/or something minor introduced by nocheck / dh_auto_test. 🤷‍♂️

I've personally successfully tested several of these versions on both s390x and arm64v8.

In general, PostgreSQL can be expected to work on these CPU architectures: x86, x86_64, IA64, PowerPC, PowerPC 64, S/390, S/390x, Sparc, Sparc 64, ARM, MIPS, MIPSEL, M68K, and PA-RISC

So, it looks fine to me to add these new arches.
