It's not good for an inherited child constraint to be marked connoinherit; that would result in the constraint not propagating to grandchild tables, if any are created later. The code mostly prevented this from happening but there was one case that was missed. This is somewhat related to commit e55a946a8, which also tightened checks on constraint merging. Hence, back-patch to 9.2 like that one. This isn't so much because there's a concrete feature-related reason to stop there, as to avoid having more distinct behaviors than we have to in this area.
