Is there ever a reason why you would *not* want recovery_target_timeline=latest in standby mode?
pg_basebackup -R doesn't set it. That seems suboptimal. Perhaps this could be the default in standby mode, or even the implicit default, ignoring the recovery_target_timeline setting altogether. How could we make things simpler here? -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
