In the first place, you are evidently running as superuser, which means
that has_foo_privilege will ALWAYS say 't' (except possibly if the
target object doesn't exist, in which case I think you get an error).
In the second place, trying to access another session's temp table is
unsupported.

After you've created at least one temp table, you can look at the result
of "current_schemas(true)". There's no guarantee that the schema even
exists before you've created something...

regression=# select current_schemas(true);
current_schemas
---------------------
{pg_catalog,public}
(1 row)

regression=# create temp table t(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=#
