And on long overnight flights the pilot will set the pressure altitude as high as permissible in the cabin to put the passengers to sleep to help out the cabin crew.

This is not possible on today's long haul aircraft. There is no method to adjust the cabin pressure. Pilots can manually control the outflow valve, but they would have to continually monitor the cabin pressure. That would distract the pilots from their crossword puzzles.
