You won't have to change the parameters in the function definition, instead
you can use the RENAME clause:
CREATE OR REPLACE FUNCTION add_user(user varchar(20), password varchar(20) )
RETURNS VOID AS $$
DECLARE
RENAME user TO x_user;
RENAME pa TO x_password;
BEGIN
INSERT INTO my_users(user, password) VALUES (x_user, x_password);
END; LANGUAGE plgpsql;
