I think that's a bit overstated ... we've gotten along fine with this
model so far, and I haven't seen any compelling reason to change it.
The problem at hand is not the error handling model, it's that the
postmaster environment doesn't implement the model.

Er, what's wrong with elog(DEBUG)?

Doesn't the postmaster need to reread the config file itself in order to
be sure to pass the new values to subsequently-started backends? Or is
your plan that newly started backends will always parse the config file
for themselves? In that case I'm not clear on why you care about the
postmaster environment at all.
