Go see the mingw-w64 wiki for download and install instructions.

mingw-w64 requires at least 4.5.1, older releases for 64bit uses a
different ABI, so using the new version saves you the trouble of
recompiling all your libraries.

In <http://archives.postgresql.org/pgsql-hackers/2011-01/msg02308.php>,
You used the MSYS compiler for MSYS development, wrong compiler. I
really wonder why you were able to get it.

Yes mingw-w64 can produce 64bit executables, but its a separate project
from mingw32. See <http://mingw-w64.sourceforge.net/>.

PS.
Please don't top post, it breaks threading. Thanks.
