Here's my vote! I'd *LOVE* it if I could do a simple cross-database join
(without the ugliness of dblink), it would be just awesome. Two beers for
cross-database foreign keys...

We already do use dblink extensively with a wrapper. for various reporting
functions. Since the cross-database queries are in the minority, it does
function as load balancing, even if the cross-joined queries aren't so
balanced.
