This is awkward. If you want archiving, use a command which does archiving, not /bin/true, which does nothing. Otherwise, turn archiving off and leave archive_command empty.
That is exactly how I setup a system that has archive_mode turned off. I never set archive_mode to off; as it very likely that I want to enable it in the future. When using “true” instead of off it allows the option to enabling/disabling arching without having the bounce the instance which requires scheduling downtime that is very difficult to get.
