I have to repeat it, the behave of this functions are little bit different. string_to_array and array_to_string are buggy. * it isn't support a NULL * it doesn't differentiate a empty array and NULL * we cannot to change default behave of existing functions * array_to_string is badly marked as IMMUTABLE > Do we think it is good idea to have different names for them?
