Well, those stats certainly appear to justify the planner's belief that
the indexscan needn't run very far: the one value of
parent_application_id is 1031 and this is below the smallest value of
object_id seen by analyze.  You might have better luck if you increase
the statistics target for acs_objects.object_id.  (It'd be interesting
to know what fraction of acs_objects actually does have object_id < 1032.)
