We need to look at the specific situation, not make a generic decision. If hot_standby = off, we are unable to unpause, once paused. Changing the default doesn't alter that problem. We have two choices: 1) override to a sensible setting, 2) throw an error. (2) sounds clean at first but we must look deeper. We know that the *only* possible other setting is 'shutdown', so it seems more user friendly to do the thing we *know* they want (1), rather than pretend that we don't. (1) is completely predictable and not at all surprising. Add a LOG message if you wish, but don't throw an error. -- Simon Riggs http://www.2ndQuadrant.com/PostgreSQL Development, 24x7 Support, RemoteDBA, Training & Services
