I think you mean that you do things like "sudo -iu postgres" to open an
interactive shell. Probably because you want to "cd" into the dir and "ls".
I imagine that's common, but is itself strange to me. You can just "ls" the
dir without sudo without opening an interactive shell, and do anything else,
too. Which is safer (avoids the risk of then leaving the shell opened or
running as the wrong user in the wrong window) and avoids starting down the
path of running around the system putting on different users' "hats".
System users like this are for running their specific daemon, for isolation
purposes and not for running interactive shells. It shouldn't have a password
set, either.
