I know you have already reported this upstream, but here are some
patches to silence the resulting warnings on MSVC.

Patch 0001 just silences the warnings using pragmas.

Patch 0002 is to silence the "unary minus operator applied to unsigned
type" warning globally for PostgreSQL. AFAICT, there is no equivalent
warning available on gcc or clang, so this would remain a trap on MSVC.

Patch 0003 is to silence the cross-enum comparison warnings using casts
(as you had suggested to upstream). I confirmed that this works in a
small test case on Compiler Explorer (godbolt.org) but if I push this
branch to GitHub Actions CI, the warning remains, so I don't know about
this one.
