I think he means more like:

create temporary index on permanent_table (fld_1);
select something from temp_test join permanent_table using (fld_1) where a=b;
select something_else from temp_test join permanent_table using (fld_1) where c=d;
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.
