Hi, Tom,

Ah, that did it. Both "top level" Directories are not found in
pg_database.oid, so they are leftovers from dropped databases. I deleted
them, and then the tablespace could be dropped.

Thanks a lot, Tom.

As I said the leftovers are likely to be caused by hard kills and
backend crashes, so I would not go into deeper analysis, but maybe the
finding and possibly removing of such leftovers should be half-automated
to assist server admins.
