Re: temporary indexes?

What Adrian is saying is that there is no need for "temporary" indexes. You can create the idxs on a temp table and they get dropped when you drop the table.

Something like this?:

aklaver(at)test=> create temporary table temp_test(id int, fld_1 varchar);
CREATE TABLE

aklaver(at)test=> create index temp_idx on temp_test(fld_1);
CREATE INDEX

aklaver(at)test=> \d temp_test
       Table "pg_temp_2.temp_test"
  Column |       Type        | Modifiers
--------+-------------------+-----------
  id     | integer           |
  fld_1  | character varying |
Indexes:
     "temp_idx" btree (fld_1)
