initdb uncomments certain values (ones that are dead certs for being
changed via ALTER SYSTEM subsequently like shared_buffers), and then -
bang! your next reload gets that "your postgresql.conf contains errors"

That is the reason, why I have suggested up-thread that uncommented
values should go to postgresql.auto.conf, that will avoid any such
observations for a well-behaved user.
