Using the following query,

SELECT o.persistent_key_str, o.ord_idFROM orders o 
WHERE o.ord_submitted_date in (

SELECT min(ord_submitted_date)ord_date    FROM ordersgroup by persistent_key_str) 

I was able to generate the following output:

<http://postgresql.nabble.com/file/n5828394/First_time_orders.png> 

The customer who placed two orders on the same date also appears in the
result set.

Thanks,

Ron
