It's especially postmaster.c and the related subroutines elsewhere that
I'm not happy about.  The postmaster would really need a way to report an
error to the log and continue in its merry ways.  This could probably be
encapsulated in elog() by setting a flag variable "I'm the postmaster" --
might even exit already.  Note:  In my experience, the previous suggestion
to return to the postmaster main loop on error would not really be useful.
