I believe the latter are the ones you cannot set per-backend.
If you want to be certain, look through src/backend/utils/misc/guc.c
to see which variables are marked PGC_POSTMASTER. Those are the
restart-required vars. The ones marked PGC_SIGHUP can be changed from
postgresql.conf, but not per-backend. (See comments in
src/include/utils/guc.h for the gory details.)
If you find any for which the Admin Guide is wrong or misleading,
please submit a docs patch ...
