The postgresql.conf file being modified is generated by initdb, and it's
already being customized per install by the initdb-time rules like
detection for maximum supported shared_buffers. It isn't one of the files
installed by the package manager where the logic you're describing kicks
in. The conflict case would show up, to use a RHEL example, if I edited a
/etc/sysconfig/postgresql file and then a changed version of that file
appeared upstream. Stuff in PGDATA is all yours and not tracked as a
config file.
