So, what in your opinion is the way to deal with this?  If we make it
a PGC_POSTMASTER parameter, it will have a very clear behavior and
users don't need to bother whether they have a risk of torn page
problem or not and as a side-impact the code will be simplified as
well.  However, as Michael said the people who get the benefit of this
option by disabling/enabling this parameter might complain.  Keeping
it as a SIGHUP option has the drawback that even after the user has
enabled it, there is a risk of torn pages.
