Corrupted pg_depend table maybe? You might try REINDEXing pg_depend
to be on the safe side. Also please look to see if there are any
relevant entries in it (look for objid = the type's OID, or refobjid
= 16562879 which we can see was the table's OID).

If there's no pg_depend entry then DROP TYPE should work. Otherwise
you might have to resort to manually DELETEing the pg_type row.
