Description
I have a query like this where FOO and BAR are two different Oracle databases.
select * from ( (select item_id, created_at, 'Foo' source from foo.items order by created_at desc limit 5000) union all (select item_id, created_at, 'Bar' source from bar.items order by created_at desc limit 5000) ) x where source in ('Foo', 'Bar') order by created_at desc limit 0, 500;
If I adjust the filter to only include results from the second query, I get an exception.

I noticed that if I remove the ORDER BY from the BAR query it seems to work (although obviously not the results I want).
Here is the debug plan.
