What is the parent_id field on sales_flat_order_payment table for ?
I would guess it’s the entity_id from sales_flat_order, but if I read it correctly then according to http://www.magereverse.com/index/magento-database-diagram/version/1-7-0-1 the actual entity_id on the sales_flat_order_payment table refers to the entity_id on the sales_flat_order table instead.

On our production machine, the parent_ids all match the entity_ids on the sales_flat_order_payment.
On our dev machine, some match and some do not. Is this to be expected ?

Using magento 1.7.0.1
Thanks

    The output of show create table sales_flat_order_payment; is:

    CONSTRAINT `FK_SALES_FLAT_ORDER_PAYMENT_PARENT_ID_SALES_FLAT_ORDER_ENTITY_ID` 
  FOREIGN KEY  (`parent_id`) REFERENCES `sales_flat_order` (`entity_id`) 
  ON DELETE CASCADE ON UPDATE CASCADE

    Means you are absolutely right, that parent_id references to entity_id in sales_flat_order
