Is it possible that some other process created an entry in
rel_group_user between these two queries?
 
That was, in fact, the problem.  At just the wrong time to impact one of the child databases (TAPd), but not the other two (TAPb and TAPc).

TAPd=# select * from rel_group_user
where user_id between 1100 and 1300
order by user_id;
 user_id | group_id | modified_by |       modified_on
