I think he means more like:

select something_else from temp_test join permanent_table using (fld_1) where

Yes. That's exactly what I mean: A "temporary index" on a "permanent table" , which
expires in the same manner of a "temporary table".
I misunderstood then. The only thing I can think of is to wrap in a
transaction, though that presents other issues with open transactions
and/or errors in the transaction.
