This commit bumps the runtime value of _WIN32_WINNT to be 0x0A00 for any builds on Windows. Hence, this makes Windows 10 the minimal requirement when running PostgreSQL under WIN32, be it for builds of Cygwin, MinGW or Visual Studio. The previous minimal runtime version was either Windows Vista when building with at least Visual Studio 2015 or Windows XP for the rest. Windows 10 is the most modern version supported by Microsoft, and per discussion, as we don't have buildfarm members that run older versions anymore, this is the minimal supported version that suits better for our needs. This will actually make easier the development of some patches, two being async I/O and large page handling by avoiding a lot of compatibility gotchas, on platforms that have most likely few users anyway. It is possible to remove MIN_WINNT in win32.h and the macros IsWindowsXXXOrGreater() that were used in the code at runtime to check which version of Windows was getting used. The change in pg_locale.c comes from Juan. Note that all my tests passed, and that the CI is green. The buildfarm will quickly tell if this needs more adjustments.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
