This has been the subject of discussion for many months and the
concencus was that the most effective approach was the hybrid one which
has now been moved into CVS tip. Those involved are fully aware of the
maintenance issues of implementing the wire protocol in the driver, as
well as the difficulties using libpq entirely caused (that is how the
08.01.xxxx driver works). Changing direction again simply isn't going to
happen.
