---------------------------------

             Summary: Implements function 'to_char'
                 Key: TAJO-639
                 URL: https://issues.apache.org/jira/browse/TAJO-639
             Project: Tajo
          Issue Type: New Feature
            Reporter: Seungun Choe
            Priority: Minor


Tajo has already to_char(timestamp, text)
But, someone need the others type input parameters.

to_char(int, text) / convert integer to string / to_char(125, '999')
to_char(double precision, text) / convert real/double precision to string / to_char(125.8::real, '999D9')
to_char(numeric, text) / convert numeric to string / to_char(-125.8, '999D99S')

These are returned text type output parameter.
