No error message for a wrong -s parameter

I'd like to know at once that I made a mistake in the parameter instead of getting the default output:

$ pgstat  -s tempfiles
------------ checkpoints ------------- ------------- buffers ------------- ---------- misc ----------
  timed requested write_time sync_time   checkpoint  clean backend  alloc   maxwritten backend_fsync

Told you that was the right day as I couldn't do much sport :)
