You can use pg_my_temp_schema for this purpose. It returns the OID of
the schema where temporary objects are stored for a given session.
Note that this returns InvalidOid if no temporary objects are defined.
Here is an example:
=# select pg_my_temp_schema();
 pg_my_temp_schema
-------------------
                 0
(1 row)
=# create temp table aa (a int);
CREATE TABLE
=# SELECT nspname FROM pg_namespace WHERE oid = pg_my_temp_schema();
  nspname
-----------
 pg_temp_4
(1 row)
