When a backend dies with FATAL, it writes an abort record before exiting.

Not in all cases; keep reading :-)
Want to give a clue? ShutdownPostgres is registered as an on_shmem_exit
hook in InitPostgres, and ShutdownPostgres calls AbortOutOfAnyTransaction.
PANIC is another story, but in that case the primary will go down, and
will write a new checkpoint soon after it starts up again.
