The same thing is said about other two special accounts, so they need to be checked if we really believe we need to check for LocalSystem. "The LocalService account is a predefined local account used by the service control manager." "The NetworkService account is a predefined local account used by the service control manager." But, in practice, SECURITY_SERVICE_RID has turned out to be enough. > And this implies, at least it seems to me, that trying to run Postgres as > this user is actually not something you'd want to do. Yes, I think people should avoid using LocalSystem for user services like PostgreSQL for security reasons. But the Services applet in the Control Panel allows to select LocalSystem, and pg_ctl register creates a service with LocalSystem account when -U is omitted.
