Is it true that overlapping QPI tool arguments and QPI XML configuration file attributes are the same?

I'm working on creating a script file to silently unbundle and upgrade PostgreSQL database in my environment. The Silently installing or upgrading PostgreSQL using the Qlik PostgreSQL Installer documentation mentions both a list of attributes that could be included in a command to silently unbundle and upgrade PostgreSQL database.

The arguments and attributes are largely the same. Here's the complete list of arguments and attributes:

#	QPI Tool Argument	QPI Config File Attribute	Available in Both
1	acceptQCA	N/A	No
2	iprange	IpRange	Yes
3	maxconnections	MaxConnections	Yes
4	dbinstallationpath	DbInstallationPath	Yes
5	dbdatapath	DbDataPath	Yes
6	dbbackuppath	DbBackupPath	Yes
7	listenaddresses	ListenAddresses	Yes
8	dbusername	DbUserName	Yes
9	dbuserpassword	DbUserPassword	Yes
10	dbsuperuserpassword	DbSuperUserPassword	Yes
11	dbhost	DbHost	Yes
12	dbport	DbPort	Yes
13	qpiconfig	N/A	No

11 out of 13 arguments/attributes exist in both. I'm assuming that means that those arguments/attributes can either be typed into Command Prompt manually or saved into a configuration file.

But they shouldn't be typed in both the command and config file.

Put differently, is it true that overlapping arguments and config file attributes must be provided either in a command or in config file but not in both places? Does anyone know?
