In SELECT FOR UPDATE, silently ignore null CTIDs, rather than generating
an error as we used to. In an OUTER JOIN scenario, retrieving a null
CTID from one of the input relations is entirely expected. We still
want to lock the input rows from the other relations, so just ignore
the null and keep going.
