An update.
ccache 4.6.1 was released which allows compiling postgres
I submitted a request to update the package in chocolatey.
But with the existing build system, it's no faster anyway, I guess due to poor
use of parallelism.

Currently, meson doesn't (automatically) use ccache with MSVC - see
mesonbuild/environment.py.
And CC=ccache gives an error - I suppose it should not try to pop ccache off the
compiler list if the list has only one element.

But it can be convinced to use ccache by renaming the executable to "pgccache".

This requires ccache 4.6, released in Feburary and already in choco.
Note that ccache supports neither /Zi debugging nor precompiled headers.
I'm not sure, but -Dc_args=/Z7 may do what's wanted here.
