Seungun Choe commented on TAJO-637:
-----------------------------------

Sorry, I missed some case for "0 9 and ,"
    select to_char(12345.12345, "99999")
    select to_char(12345, "99999.99999")

So, I will re-patched TAJO-637 in this week!! :)

> Currently, Tajo only supports to_char(timestamp, text) function.
> However, PostgreSQL supports to_char() for timestamp, interval, int, double, 
> and numeric types
> Tajo needs to support more data types in to_char() as shown in 
> http://www.postgresql.org/docs/9.3/static/functions-formatting.html
