After going through the installation of a Windows setup with meson and
ninja under VS, I have checked that this is working correctly by
myself, so I am going to apply that. One of the tests I have done
involved feeding a dump of the regression data through a pipe to
pg_restore, and the whole was able to work fine, while head broke when
using a pipe.

Digressing a bit, while I don't forget..

Spoiler 1: I don't think that recommending ActivePerl in the
documentation is a good idea these days. They do not provide anymore
a standalone installer that deploys the binaries you can use, and
they've made it really difficult to even access a "perl" command as it
has become necessary to use an extra command "state activate
--default" to link with a project registered in their stuff, meaning a
connection to their project. Once this command is launched, the
terminal links to a cached state in AppData. This is very unfriendly.
In comparison, relying on StrawberryPerl and Chocolatey feels like a
breeze..

Spoiler 2: mingw.org seems to be dead, and we have two links in the
docs referring to it.
