You can use schema name as a prefix:
postgres=# \d+
List of relations
Schema | Name | Type | Owner | Size | Description
-----------+------+-------+----------+------------+-------------
pg_temp_1 | t | table | postgres | 8192 bytes |
(1 row)
postgres=# drop table pg_temp_1.t;
DROP TABLE
But generally speaking I suggest you generate random names for
temporary tables.
