Hi to all!
    I have created a table using the CREATE TABLE new_table (col1,col2,col3)
AS SELECT col1,col2,col3 FROM org_table.
    I create an index on this table using the statement:
CREATE UNIQUE INDEX table_idx ON new_table (col1).
    Then i do a select as this:
SELECT * FROM new_table WHERE col1 = 'value'.

    The problem is that when i do an explain this is the query plan:

Seq Scan on new_table  (cost=0.00..1116.38 rows=500 width=44)


Can anyone explain me why it doesn't use the index I have created?

Thank you for you help...

Bye, Denis
