That actually depends on your windows version :-) See for example
http://weblogs.asp.net/pwilson/archive/2003/06/24/9214.aspx.
You might be able to get around this using a manifest file, or you can
change the search order using something like
http://www.windowsitpro.com/Article/ArticleID/26222/26222.html. This
really isn't a problem as long as you're on a server where no untrusted
users are allowed.
I think the long-term change may be to not call it libpq but instead
"libpq2" or something if a non-backwards-compatible version is made.
