Keuntae Park commented on TAJO-361:
-----------------------------------
Actually, in rpad(string text, length int [, fill text]),
'length' value can be smaller than the length of 'string'.
In that case, rpad should truncate the 'string'.
For example, rpad('hi there', 3) should return 'hi '.
But, this patch does not account for that case.
And, when 'fill' is not specified, space character should be used as default
value.
I think you need to consider above two points.
