Well putting configuration files in PGDATA is itself a packaging
violation. I'm talking about /etc/postgresql.conf. Yes it's possible
for packages to simply opt out of the configuration file management
which at least means they're not actively causing problems -- but it's
a cheat, it means it's giving up on providing the user with useful
upgrades of configuration files.
