 No, I don't want the trigger to do any db stuff at all. Basically, I've
got a content management system that is going to be split across a
cluster. Upon an update submission from one of them, I want to replicate
across the others (which can happen in pseudo real time). So, basically
the DB is the master, once it makes an update, it will spawn a process
to the syncronization (all of this code is written). I just don't want
the initial update process to wait for replication to finish (which is
only a second or two under normal load). I could write a daemon that
would sit an listen to these replication requests, but that just seems
to be more complex than I need.

Cheers,

Chris
