problems with TEMP table (6.5.3)

I have a problem with 6.5.3 and TEMP table inside transaction.

test=> begin;
BEGIN
test=> create temp table tempid (id int, level int);
CREATE
test=> \q

Postgres process doesn't stopped. The same happens if I
use rollback before ending transaction.

test=> \d
Couldn't find any tables, sequences or indices!
test=> begin;
BEGIN
test=> create temp table tempid (id int, level int);
CREATE
test=> insert into tempid ( id, level ) values (1 ,1);
INSERT 332330 1
test=> rollback;
ABORT
test=> end;
NOTICE: EndTransactionBlock and not inprogress/abort state
END
test=> \q

zen:~/app/pgsql$ psql test

test=> vacuum;

ERROR: cannot write block 0 of pg_temp.8928.0 [test] blind
test=>

I checked 7.0 from cvs and it looks better.

Also, I see a lot of opened files when doing
select/inserts into temp table inside transaction
(temp table was created before transaction). So,
if I do a lot of selects/inserts I easily reach file description limit.

Do I miss here ?

Regards,

Oleg
