Here it is. Remove or rename the current interfaces/libpq++ and untar

this file in interfaces/

It will all need to be checked in.  I used the char *rcsid[] method for
cvs ids so it can be strings | grep'd to find version numbers.  The new
version for the library is 3.0.

Run configure from src/ to create the Makefile and it should be good to
go.

I did minimal documentation references in the README, I'll see if I can
get something to Tom Lockhart rather quickly.
