For what reason I cannot use a Windows domain user to run APM Postgres database?

I am on Windows, and the EM installer creates the user for running APM Postgres database.  I would like to change the user to a Windows Domains user afterwards.


After the installation of the APM Postgres database on Windows, if I want to change the default user to a Windows domain user to run the APM Postgres database, why is that not supported and what issues could I run into?

Windows; APM database on Postgres

A foreseeable issue is one that would occur during uninstallation/upgrade of EM(DB). 
Reason: during installation we provide postgres as admin, but when we modify this credential using the Windows domain user, the uninstallation script, which is necessary in the upgrade process, will likely fail.

Hence, it is not supported and not recommended.
