Still works (though only shows creation, not deletion).

My best guess would be your queries are happy enough with your current work_mem setting.
With the default value, an easy enough example that shows such a message is:
create table t1(id integer);
insert into t1 select generate_series (1,1000000);
select * from t1 order by id;
With the last query, you should get a temporary file log message in your log file.
