Thanks to Ian for prompting me to pick up this thread again; apologies for getting distracted. The attached patch is a reduced version of the original. It covers only: * deprecation of the promote_trigger_file - there are no tests that use that, hence why there is no test coverage for the patch * changing the sleep time of the startup process to 60s * docs and comments Other points will be discussed in another branch of this thread. -- Simon Riggs http://www.EnterpriseDB.com/
