\dt and pg_user problems

Hi everybody,

I updated my postgres V6.4.2 to V6.5.2 and i'm facing with two problems
(maybe only one).

First, using psql if i use the command \dt i recive the message

" Couldn't find any tables ",
but is i use the query
SELECT * FROM tablename
i can get what i need, also the command \d tablename works fine.

Second, even if all users are in pg_shadow they don't appear in pg_user.

I thought that initdb failed to create the rule for pg_user, so i tried to
execute this

**************************************************
CREATE RULE _RETpg_user AS ON SELECT TO pg_user DO INSTEAD SELECT usename,
usesysid, usecreatedb, usetrace, usesuper, usecatupd, '********'::text as
passwd, valuntil FROM pg_shadow;
*****************************
by hand, but i recieved the following error message:
view rule for pg_user must be named _RETpg_user.

Is there someone who can help me to fix this?
Thanks in advance.
Best regards,
