Re: list of sequences

I would think that using a replicator which reads the logs would work
better. How are you going to deal with serialization ? Also you need to
worry about changes made manually in the db?

Regarding the serialization you could have two processes which both
attempt to execute select * from foo from update simultaneously. The
server will serialize these properly, your code may not.
