Not currently. In 9.5 it'll be possible to do UPDATE test_update_m_values SET (gid_plus_1,gid_minus_1) = (select * from rc_test_update_m_values(gid));
but the syntax you were trying will never work, because it would be ambiguous with the case of assigning a composite value to a single composite column.
