Add support for ARM64(AARCH64) architecture

[ybkimm]

I have compiled this project on an ARM64 device, and I got this error:

          ^~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

... and atomics.h seems to support ARM devices.

#if defined(__arm__) || defined(__arm) || \
        defined(__aarch64__) || defined(__aarch64)
#include "port/atomics/arch-arm.h"
...

I found arch-arm.h on PostgreSQL repository:

• https://github.com/postgres/postgres/blob/master/src/include/port/atomics/arch-arm.h

After adding this file, I was able to compile without any problems.

Is there any reason not to support ARM(and other architectures)? if it doesn't matter, can you add support for architectures other than x86?

I have the same issue and I used the same fix as @ybkimm.

If you want to add ARM support, I can open a pull request.

Oh, would you do that? Thank you for your help.

Same issue with the pg_query gem.

Fixed with https://github.com/lfittl/pg_query_go/commit/f8446ec142daf925958b846d49dfcdaca96f8b07 - thanks for everyone's patience on this!
