I'm no PL/PgSQL expert, but I think that you cannot do transactions within a
function (this is because postgres doesn't support nested transactions.

However, since the function will run inside a transaction anyway, just do
this:

CREATE FUNCTION simple_fun() RETURNS INTEGER AS '
BEGIN SELECT 1; RETURN 1;
END;
' LANGUAGE 'plpgsql';

Now, of course you can't do your isolated transaction, so you'll need to
create the function above and then use it like this:

BEGIN;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SELECT simple_fun();
COMMIT;
