VIEWs and TEMP tables problem

Hi!

I found a problem with the views in PostgreSQL if I want to use
temporary tables in it. See the next case!

CREATE TABLE a(...., code INT4,...);
INSERT INTO a(...,code,...) VALUES (...,23,...);
CREATE TABLE actual_code(code INT4);

If I execute the next query, the result is empty.
SELECT * FROM actual_code;

CREATE VIEW a_view AS SELECT * FROM a JOIN actual_code AC ON (a.code =
AC.code);

CREATE TEMP TABLE actual_code AS SELECT 23::INT4 AS code;

If I execute the next query, the result contains exactly one row (code:
23). This is perfect.
SELECT * FROM actual_code;

After it if I compare the the next two queries, there will be
differences in the results.

1) SELECT * FROM a JOIN actual_code AC ON (a.code = AC.code); (Result
has one row!)
2) SELECT * FROM a_view; (Result is empty!)

In my opinion this queries should be equivalent with same results.
The problem is that the view use the original permanent table, but the
1) query use the temporary actual_code table.
I read the temporally table definition in the documentation
(http://www.postgresql.org/docs/8.1/interactive/sql-createtable.html)
and I concluded it should be working.

Is it BUG, or FEATURE? Has anybody got good ideas for solve this problem?

This construction came to my mind, because I tried to solve my another
question:

Thanks your ideas!
