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)
