Not if you link libpq as a static lib...
I *think* that's why it was added. In the beginning it was only in the
DLL attach code, and if you were using the library as a static lib you
had to call it yourself. Not sure when that changed, but clearly that is
when the WSACleanup() call should've gone in.
