Ahhh... Here's an example using Tom's recommended field=ANY (arrayvalue) SQL.
CREATE TABLE ids
( id INTEGER , PRIMARY KEY (id)
);
INSERT INTO ids VALUES (1);
INSERT INTO ids VALUES (2);
INSERT INTO ids VALUES (3);
CREATE OR REPLACE FUNCTION example_array_input(INT[]) RETURNS SETOF ids AS
$BODY$
DECLARE in_clause ALIAS FOR $1; clause TEXT; rec RECORD;
BEGIN FOR rec IN SELECT id FROM ids WHERE id = ANY(in_clause) LOOP RETURN NEXT rec; END
LOOP; -- final return RETURN;
END
$BODY$ language plpgsql;
SELECT * FROM example_array_input('{1,2,4,5,6}'::INT[]);
