Обсуждение: pgsql: Back-patch fixes for some issues in our Windows socket code into

Back-patch fixes for some issues in our Windows socket code into 9.1.

This is a backport of commit b85427f2276d02756b558c0024949305ea65aca5.
Per discussion of bug #4958.  Some of these fixes probably need to be
back-patched further, but I'm just doing this much for now.
