You are right! I misremembered. It's `ps x`.

From `man ps`:

       x      Lift the BSD-style "must have a tty" restriction, which is imposed upon the set of all processes when some BSD-style (without "-") options are used or when the
              ps personality setting is BSD-like.  The set of processes selected in this manner is in addition to the set of processes selected by other means.  An alternate
              description is that this option causes ps to list all processes owned by you (same EUID as ps), or to list all processes when used together with the a option.
