libpq++ in 7.3?

Is it an accident in the documentation on the web site?
Or does postgres 7.3 not provide a C++ interface
library?

I remember reading discussions about libpqxx being
proposed as a replacement for libpq++, but I don't
know if it did indeed replace it, or if that has
anything to do with the missing libpq++ in the
documentation.

Thanks,

Carlos
