possible repalloc() in icu_convert_case()

Hello,

in src/backend/utils/adt/formatting.c, in icu_convert_case() I see:
     if (status == U_BUFFER_OVERFLOW_ERROR)
     {
         /* try again with adjusted length */
         pfree(*buff_dest);
         *buff_dest = palloc(len_dest * sizeof(**buff_dest));
         ...

Is there any reason why this should not be repalloc()?

In case it should be, I've attached a corresponding patch.
