I wonder why the contrib modules can be compiled correctly because:
    1. PG_MODULE_MAGIC requires dllexport.
    2. Other exported variables from postgres requires dllimport.
    3. Exported functions from the contrib DLLs require dllexport,
       but they don't have any PGDLLEXPORT tags in their functions.

Did we use non-standard tools except msvc in the build frameword
for core code? And what should I do for an external project?
