[repost] pg_restore doesn't work with custom format?

This looks like a bug, or can somebody explain how I'm supposed to
restore a custom archive dump?

$ createdb foo
CREATE DATABASE
$ psql foo
foo=# create table users (id serial);
NOTICE: CREATE TABLE will create implicit sequence 'users_id_seq' for
SERIAL column 'users.id'
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'users_id_key'
for table 'users'
CREATE
foo=# \q
$ pg_dump --blobs --clean --create --file=/tmp/foo.dump --format=c
--compress=9 foo
$ dropdb foo
DROP DATABASE
$ pg_restore --create -d test /tmp/foo.dump
Archiver(db): Could not execute query. Code = 7. Explanation from
backend: 'ERROR: ProcedureCreate: procedure pltcl_call_handler already
exists with same arguments
'.
$ pg_restore --create --clean -d test /tmp/foo.dump
Archiver(db): Could not execute query. Code = 7. Explanation from
backend: 'ERROR: index "users_id_key" does not exist
'.

What's the magic command that I am looking for??
