> (making issue from a user question in Tajo user group)
> Some built-in string functions accept only "text" type argument, 
> eg. TEXT upper(text), INT4 char_length(text)
> so they require explicit type casting to be used for char, varchar columns.
> For user conveniences and compatibility to legacy SQL statements, it would be good to support parameter overloading for those built-in functions.
