I am creating a table with an identity column and later drop the table. The sequence associated with the identity column, however, is not dropped. This behavior is different from what I have observed in 19c.

Is this a bug or am I missing something.

The following statements reproduce the behavior on my system:

create table T (
  id   integer generated always as identity
);

drop table T;

select
  (sysdate - created) * 24*60*60 created_secs_ago
from
  user_objects
where
  object_type = 'SEQUENCE' and
  (sysdate - created) * 24*60*60 < 2;
