We already have a way to find out your temp table schema name:
current_schemas.

regression=# create temp table foo(f1 int);
CREATE TABLE
regression=# select current_schemas(true);
current_schemas
-------------------------------
{pg_temp_1,pg_catalog,public}
(1 row)

regression=# select (current_schemas(true))[1];
current_schemas
-----------------
pg_temp_1
(1 row)

regression=# select relname from pg_class c join pg_namespace n
regression-# on relnamespace = n.oid
regression-# where nspname = (current_schemas(true))[1];
relname
---------
foo
(1 row)

I don't think it's reasonable to complicate \dn so much in order to
provide an alternative way of learning your temp schema name.
