When pulling a "postponed" qual from a LATERAL subquery up into the quals of an outer join, we must make sure that the postponed qual is included in those seen by make_outerjoininfo(). Otherwise we might compute a too-small min_lefthand or min_righthand for the outer join, leading to "JOIN qualification cannot refer to other relations" failures from distribute_qual_to_rels. Subtler errors in the created plan seem possible, too, if the extra qual would only affect join ordering constraints. Per bug #9041 from David Leverton. Back-patch to 9.3.
