Why is user_1’s insert on the referencing table failing? Is the validation of the FK no longer done as user_1? Exactly, it's done as the owner of the referencing table. (I don't recall whether that's uniformly true for all types of FK-enforcement queries, but evidently it's true for this case.) regards, tom lane
