That would certainly help.  I don't know that it needs to be technically
'trivial', but at least having check_postgres.pl or something which can
alert on it would be an improvement.  Clearly, that would be valuable
today (assuming it doesn't already exist somewhere..  it might).

That an interesting notion; do you have something specific in mind..?
The easiest, imv anyway, would be that options set in postgresql.conf
can't be overridden, but that gets us into the bootstrap problem that
people seem to be concerned about.  It would also be a change to how
postgresql.conf is parsed today which some people would be annoyed by.
Having some configuration option which says what can be modified by
alter system doesn't strike me as a terribly good solution either.
