I just successfully compiled postgres with meson and readline, using msvc, only tweaking psql_completion() contents.
The readline I used for building with msvc is from vcpkg.exe install --triplet x64-windows readline-win32 pkgconf ... # when running tests, the readline dll needs to be somewhere in PATH $ENV:PATH="$ENV:PATH;c:/dev/vcpkg/installed/x64-windows/debug/bin"

Andres,
Thank you for this. I Will dig into it.
A note on using readline.dll... We have to be careful, this was one of the issues I had.
Readline uses it's own xmalloc() to allocate the line, and in our mainloop, we get that as "line",
and then we call free(line); which triggered Assertion Failures. I've always thought it was not a
great pattern to allocate inside the DLL and free inside the application, unless you can
