I think it must be using a seqscan for the foreign key check query.
Could you try this and show the results?
prepare foo(my.dint) as
SELECT 1 FROM ONLY "my"."large" x WHERE "small_id" = $1 FOR UPDATE OF x;
explain analyze execute foo(239);
When I try it I see an indexscan plan, but maybe there's some aspect of
your setup that's causing problems.
