What are you trying to do?

Temporary tables are stored in the pg_temp_NNN schema (e.g.,
pg_temp_1).  See the "System Catalogs" chapter in the PostgreSQL
documentation for information on finding a table's schema.  If
you're using 7.4 or later then see also the "Information Schema"
chapter -- one of its views has two fields that should be helpful.
