I think I misunderstood your original request on that. Because you are just talking about returning a timestamptz with the "right now" value for when you called pg_stop_backup()? Or to be specific, just before pg_Stop_backup *finished*. Or do you mean when pg_stop_backup() started? Doing it in the backup label file is obviously a different target, where we might need to consider backwards compatibility, Should we? > * It seems like STOP WAL LOCATION should now also be recorded in the > label file.

Doesn't mean it shouldn't be done, but that's a separate thing. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
