No, you're missing the point. If the postmaster goes down there's no hope of automatic recovery from the situation. If the replication manager is separate, and it crashes, then the postmaster can kill all the backends and auto-restart the whole thing. This architecture has served us very well for years and I think you're making a serious mistake to change it. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
