\df billing_days                                     List of functions Schema |     Name     |     Result data type

--------+--------------+--------------------------+--------------------------------+-------- public | billing_days |
TABLE(billing_datedate) | start_date date, 
 
end_date date | normal


select * from billing_days('05/01/2017', '05/30/2017'); billing_date
