But does this mean that postgresql.conf will be reread globally (i.e., by
the postmaster), when the user signals HUP only to a single backend?  I
guess this is actually a good idea, but it would be a change of
functionality.  Admittedly, the window of utility of signalling only a
single backend is small, but let's make sure the hupping behavior is
correctly documented, because this is possibly not expected.
