Thanks for the advice, guys. After fiddling around with it a bit, I
went for the age-old solution of changing the data and the

Thanks,
Colin

I'm writing a messaging system, and I have the following problem. I
have a conversations table, and a messages table that has a foreign
key to conversations. I can do something like the following to provide
a summary:
select conversation_id, count(*), max(unread), max(updated_on)
from messages
