Bucardo and pg_pool are both based on the idea of replaying SQL

Actually, Bucardo is very data-based, not statement at all. It stores up
a list of affected rows, then COPYs those from the source databases
to the target ones. It's particularly strong when you have large
delays and many updates to the same row.
Doh! My apologies.
