The worst part of the scalability issue is that if "If the day comes on the eve" it has been years since they have done nothing on interact indexes, in fact, they rejected the development even when Alvaro Herrera showed performance gains of 3x and wal generation advantage above 4x. The xid are still 32 bits by the way, in a day and age where many architectures have already or are preparing to drop 32 bit support (not numbers, clearly, architecture). The situation with the stubborn attitude remembers me of the dead or Perl.
