The `postgresql-upgrade` script will now run any executables located in the `/etc/postgresql/post-upgrade.d` directory. This will allow making arbitrary changes to the system after a PostgreSQL major version upgrade. Notably, we will use this capability to change the WAL-G configuration to upload WAL archives and backups to the correct version-specific location.
