libpq++.h contained copies of the class declarations in the other libpq++ include files, which was bogus enough, but the declarations were not completely in step with the real declarations. Remove these in favor of including the headers with #include. Make PgConnection destructor virtual (not absolutely necessary, but seems like a real good idea considering the number of subclasses derived from it). Give all classes declared private copy constructors and assignment operators, to prevent compiler from thinking it can copy these objects safely.
