My understanding is that when postgresql is shutdown it triggers a checkpoint which triggers the archiving of completed tx logs. Will the "pg_ctl stop" command wait for archiving to complete or is the act of archiving completely asynchronous from the shutdown process?
In my case, I WANT the pg_ctl command to hang until all files are archived because immediately after I issue "pg_ctl stop" I want to be able to unmount the disk that the archived logs are being copied to.
