plpgsql will reject UPDATE RETURNING INTO that returns more than one
row, since it hasn't got any place to put the additional data.
It wasn't clear to me whether the OP was even using plpgsql, but if he
was, the example should have worked. We'd need to see more detail to
guess what the real problem is.
