pg_restore, search_path and operator class

["Jozsef Szalay" <jszalay@xxxxxxxxxxxx>]

Hi,

I've searched the archives for this issue but I could not find an
answer. I apologize if this has been beaten to death already. 

Postgresql version:
====================
8.1.2 on Linux

The issue:
===========
I've got a user defined data type that has been defined in the "public"
schema. I use pg_dump to dump a table that has a column of this type:

create myschema.mytable (id public.mytype primary key, name varchar);

pg_dump -U user --schema myschema --table mytable -f mytable.dump mydb

When I try to restore this table with psql

psql -U user -d mydb -f mytable.dump

I get an error

SET
SET
SET
SET
SET
SET
CREATE TABLE
ALTER TABLE
psql:mytable.dump:48: ERROR:  data type public.mytype has no default
operator class for access method "btree"
HINT:  You must specify an operator class for the index or define a
default operator class for the data type.

This error is not correct because "mytype" does have a default operator
for btree:

CREATE OPERATOR CLASS public.mytype_ops_btree DEFAULT FOR TYPE
public.mytype USING btree AS...

I've included the content of the dump file at the bottom of this email.
Note that, at line 11, there is a SET search_path statement, which does
not contain "public". If I change the search_path to include "public"

Set search_path = myschema, public, pg_catalog;

everything works fine. Is there a way to force pg_dump to include
"public"? How should I change my operator classes or data type to make
this work? (Moving the data type to pg_catalog works but we've got a lot
of data out there to migrate.)

Thanks for the help!
