A general purpose log miner is also useful in many other areas besides replication.

While this code might be useful, whouldn't it be much more valuable to provide hooks into xlog so that we could do non-trigger-based replication? (As well as non-trigger-based materialized views...)
If we're going to do hooks for replication, I think we should look at including xlog. Trigger-based replication is an OLTP performance killer if you're just looking to do async replication.
