- 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
and replaced by GetLatestXTime() but this function cannot
be called from external programs.
Instead now we are using GetXLogReceiptTime() which tells
us what was the last time we got a WAL record by streaming
or file.
