Well, that just doesn't seem useful to me in the real world. If I were
using this, I would expect it to emit a real user name that matches the
currently applied permissions checking. All the time. "show role" does
what it does because the SQL standard says so, not because anybody
outside the standards committee thinks that's a sane definition.
