Recently upgraded PostgreSQL from version 9.5 to version 9.6. When updating, I used links to the old cluster. Now, when the database is deleted (tried through pgAdmin4 and through psql), the database is deleted, but the disk space is not released.

pg_upgrade --link ?
Useless datadir from 9.5 removed? pg_upgrade created a delete_old_cluster script after the upgrade to do this.
