postmaster.opts | A file recording the command-line options the postmaster
was last started with

So two inconsistences:
(1)  not necessarily postmaster;
(2)  if I starup postmaster by pg_ctl, then the information is not recorded
here.

Am I misunderstand something obviously?

Apparently, because your example fails to demonstrate either of the
claims you make.  AFAICS pg_ctl started the postmaster with exactly
the argument that the file says.
