I have searched and searched and just cannot find the maximum lengths for input variables in a function
i.e.
CREATE FUNCTION test(input1 char(5), input2 varchar(50)) RETURNS void AS $$RAISE NOTICE('%,%'), $1, $2;$$ LANGUAGE plpgsql;
Where do I find the 5 and the 50 it has to be somewhere I have searched through pg_proc pg_type pg_attribute (whose attlen only relates to tables) pg_type
and all possible manner of joining these tables.
Hmm. I only looked at the code and hence don't have a definite answer. But it seems that information is not stored anywhere. That might explain why the function you mentioned accepts parameters with any character length.
