SYSTEM_USER is the operating system user that connected to the database
system. This is obviously not generally applicable in the environment
PostgreSQL runs in, nor is there a universal and reliable way to get this
information, so I suggest we don't bother about it. Mapping it to
[CURRENT_]USER would certainly be wrong.
