You can use DO block if your postgres version is >=9.0.

DO $$
DECLARE _tablename text
BEGIN
    FOR
        SELECT INTO _tablename tablename
        FROM pg_tables WHERE schemaname = 'schemaname'
    LOOP
        EXECUTE 'CREATE RULE ... TO $1 ...' USING _tablename;
    END LOOP;
END $$;

For <9.0 you can use shell script with psql to do the same.

For pre-9.0, just explicitly create, run, and drop a pl/pgsql function.  Much easier than a shell script.

Best Wishes,
