Could we hide the table name listing from unprivileged user?

Hi,
A problem we are facing is although we revoke all from
one database user, he can still see the table exists
in psql using \dt command, but he can'd select * from it
of course, how could we hide the table name listing from
him?

We are using 7.4.x and 8.0 beta, with ODBC, JDBC and libpq.
