I think this idea is worth thinking about. I don't think this should be specific to a time-based recovery target. This could apply for example to a target xid as well. Also, there should be a way to get the old behavior. Perhaps this whole thing should be a new recovery_target_action, say, 'pause_unless_reached'. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
