Patch for incomplete libpq DLL .def file

I have ported another Python Postgres interface to Windows (PgSQL). It seems
that not many people actually use libpq on Win32; I have found another bug. Some
functions that are defined in libpq-fe.h aren't exported in the DLL version of
the library. I have added them to src/interfaces/libpq/libpqdll.def. The new
complete file is attached.
