Re: archive_cleanup_command when is called?

Sameer,
since the issue happens in a production environment, I cannot perform
these kind of tests.
For the moment I will disable the PITR archiving and go on only with
the Streaming Replica.
I will try to replicate the issue in a DEV environment.
Thanks.
