Thanks, Erik another possible solution would also be this.

Here it is in case you are interested.

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[]);
