Is it possible to pass the NULL value to PL/pgSQL function? More precisely,
I have a function like
CREATE FUNCTION test (text,int4) RETURNS int4 AS '
Begin
...
End;
' LANGUAGE 'plpgsql';
and typical call is
select test('Word',1);
which works fine. But sometimes I need to call this function with
arguments like
select test(NULL,1); or
select test('Word',NULL);
Now such calls lead to
ERROR: typeidTypeRelid: Invalid type - oid = 0
Any ideas?
