What i did so far:
$ REINDEX TABLE pg_depend
$ SELECT * from pg_depend where objid = 16562879;
classid | objid | objsubid | refclassid | refobjid | refobjsubid | deptype
---------+-------+----------+------------+----------+-------------+---------
(0 rows)
$ SELECT * from pg_type where typname = 'temp_gc';
typname | typnamespace | typowner | typlen | typbyval | typtype | typisdefined
| typdelim | typrelid | typelem | typinput | typoutput | typreceive |
typsend | typanalyze | typalign | typstorage | typnotnull | typbasetype |
typtypmod | typndims | typdefaultbin | typdefault
---------+--------------+----------+--------+----------+---------+--------------+----------+----------+---------+-----------+------------+-------------+-------------+------------+----------+------------+------------+-------------+-----------+----------+---------------+------------
temp_gc | 16847 | 100 | -1 | f | c | t
| , | 16562879 | 0 | record_in | record_out | record_recv |
record_send | - | d | x | f | 0 |
-1 | 0 | |
(1 row)
$ DROP TYPE temp_gc;
ERROR: type "temp_gc" does not exist

There is no pg_depend entry as far as i can tell, but DROP TYPE doesn't work.
Can i just DELETE the pg_type row now??
Sorry for asking again and again, but manipulating system catalogs seems to me
very dangerous. It's live database and i dont want to do anything wrong.
kind regards
