If a rule action contains a subquery that refers to columns from OLD or NEW, then those are really lateral references, and the planner will complain if it sees such things in a subquery that isn't marked as lateral. However, at rule-definition time, the user isn't required to mark the subquery with LATERAL, and so it can fail when the rule is used. Fix this by marking such subqueries as lateral in the rewriter, at the point where they're used. Dean Rasheed and Tom Lane, per report from Alexander Lakhin. Back-patch to all supported branches.
