- Add checks to test if the directories are useful for us (basically the checks follow the same approach as initdb does) - Add connection parameters - Better use of rsync - Some more clean up of code Changes in repmgrd are: - Add a parameter to allow the user specify an repmgr.conf - Change the name of the repl_status table for repl_monitor - Create a repl_status view that also shows lag in time - Some more clean up of code
