I have the following function, which receives an array of ints, iterates it calling other function:

```
CREATE FUNCTION calculateAbsencesForIDs(INT[]) RETURNS TEXT AS 
'
DECLARE
  index integer := 0;
  resultArray decimal[];
  id int;
  result text;
BEGIN
  FOR id IN SELECT $1 LOOP

        resultArray[index] = calculateAbsenceForID(id); 
        index := index + 1;

END LOOP;
RETURN array_to_string(resultArray, result);
END;
'
LANGUAGE plpgsql;

```

I try to call it using:

```
SELECT calculateAbsencesForIDs(ARRAY[85,74,75,76,77,78,79,80]);

```

or

```
SELECT calculateAbsencesForIDs('{85,74,75,76,77,78,79,80}');

```

or

```
SELECT calculateAbsencesForIDs('{85,74,75,76,77,78,79,80}'::int[]);
...

```

But I have always the same error:

```
[Error Code: 0, SQL State: 22P02]  ERROR: invalid input syntax for integer: "{85,74,75,76,77,78,79,80}"

```

I don't know how I can call this function. I have looked in postgres docs, I think this is correct but it doesn`t work.
