When someone issues pg_ctl -m immediate stop (which is the immediate shutdown). pg basically shutd backends in their
head.This, in turn, means that all other have to exit to avoid shared memory corruption.
 

Sometimes such exit happens before pg_ctl will kill next backend, sometimes not. So you sometimes can get such
messages.
