Well, the thing that was annoying me was that because a backend saw one
value in postgresql.conf as incorrect, it was refusing to apply any
changes at all from postgresql.conf. And worse, there was no log entry
to give any hint what was going on. This doesn't seem to me to have
much to do with the problem you're on about. I agree it's conceivable
that someone might think of a way to solve both issues at once, but
I think we'd better list them as separate TODOs.
