Previously, the Windows MSVC build generated pg_config.h from a hard-coded pg_config.h.win32 with some ad hoc postprocessing. The pg_config.h.win32 file required manual maintenance and was as a result frequently out of date. Instead, have the MSVC build scripts emulate what configure and config.status do: collect a list of defines and then create pg_config.h from pg_config.h.in by changing the appropriate lines. The previous setup was made to support old Windows build systems that didn't have any text processing capabilities, but the current system has Perl, so it's not a problem. pg_config.h.win32 is removed. In order to try to keep the Windows side of things more up to date in the future, we now also require that all symbols found in pg_config.h.in are defined in the MSVC build system. So if there is a change in configure that results in a new symbol, an update in Solution.pm will be required. The other headers managed by AC_CONFIG_HEADERS in configure, namely src/include/pg_config_ext.h and src/interfaces/ecpg/include/ecpg_config.h, get the same treatment, so this removes even more ad hoc code in the MSVC build scripts.

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/.
