Thanks for your works!

Although I have some comments, it's ok after the RC version is released because it's trivial things.

Please add commit message the deatailed reason why you change the code because mainteners may change. For example, I think the following things are important.

• why do we change to pg_backup_start()/pg_backup_stop() and the arguments are changed? In my understanding, though the exclusive mode is remove, it just renames the function name and keeps the behavior because pg_rman already changed to use non-exclusive mode.
• why the arc_srv_log_management.sh change the log_checkpoints = off? In my undersanding, the reason is that the test to check if the expected server logs are removed fails since the default value bacame 'on'. The checkpoint logs update the timestamp of server log files when executing the test, and it makes remove newer dummy server logs. To avoid the behavior, turn it off only when the tests are executed.

I changed commit message.
