After discussing the topic in-person with Peter at FOSDEM. We agreed
that the best road forward was to not bother with MSVC for now. No-one
has actually expressed an interest in being able to build C++ extension
using MSVC, and the effort to support it is both non-trivial and not
without downsides to the rest of the codebase. We can always come back
to this later, possibly requiring C++20 on MSVC.
So I've removed that patch and now this patchset its goal is to improve
compatibiltity with the C++ flavor of GCC and Clang.
Patch 1 and 2 add some more macro calls to our test C++ extension. These
macros already work in GCC and Clang, this is purely to test for future
regressinos.
Patch 3 makes copyObject work when using GCC or Clang with -std=c++11 by
introducing pg_exprtype.
Patch 4 starts using pg_exprtype in more places.
I'm also working on some patches to support
StaticAssertVariableIsOfType, but I've run into some ICE compiler errors
of MSVC 2019.
