And that's actually one of the issues that I have with this overall
approach.. If configurations can be set in 'data' areas which prevent
the system from starting, that's *bad*. Very bad. It means people will
not be able to trust PG to manage the configuration sanely and will have
a lot of distrust and fear of the ALTER SYSTEM capability.
Requiring users to go monkey around inside of a system data directory to
clean things up in order to get PG to come up is a situation we should
do our best to prevent from ever happening.
