- 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
Also remove get_last_xlog_replay_timestamp() function and the sql_utils dir,
we can readded later if we need.
We don't need the column last_wal_standby_timestamp in repl_status, so
remove it
