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.
Thanks,
