Thom,

Valuable information, thanks. I try to get the table structure correct
before loading it into a database. In this case I was copying structure
(with minor mods) from an existing environmental database and it took me a
while to notice the original authors used synthetic keys when they are not
needed. So, I got rid of those keys.
