tables are not listable by \dt

Hi, we recently upgraded our Postgres instllation from 7.4 to 8.2 by
doing a dump and restore. Howveer after logging into the database (as
a user that is not the superuser) and doing \dt I get the error:

No relations found

But when I do

SELECT relname, relpages FROM pg_class ORDER BY relpages DESC;

I get a list of the tables and their sizes.

I'm not even sure where to begin looking for the solution and any
pointers would be much appreciated.
