I did not mean that they don't require an argument. What I was trying to
refer is that "pg_ctl status" would not require a "-m fast", for instance.
Would there be a functional difference if I execute following commands:

pg_ctl status -D data/ -m fast
pg_ctl status -D data/ -m smart
pg_ctl status -D data/ -m immediate

If no, then -m does not seem a valid option for "pg_ctl status".But I am
allowed to execute all of the above.
