Good :-)

Microsoft have changed things so that you now have multiple versions
of the runtimes installed side by side without them conflicting with
one another - we use the latest (SP1) version (8.0.50727.762) with
PostgreSQL - something else has presumably added the earlier verison
you also have (8.0.50727.163). Any machine using libpq (client or
server) or any part of the server will need the correct version of the
runtimes to be installed.

You can avoid this by building your own libpq.dll using mingw/msys if
you like - that will work just fine with a VC++ built server.
