Bug Fixes:
- Fixed the check command to prevent an error message from being logged if the backup directory does not exist. (Fixed by Cynthia Shang.)
- Fixed error message to properly display the archive command when an invalid archive command is detected. (Reported by Jason O'Donnell.)
- Fixed an issue where the async archiver would not be started if archive-push did not have enough space to queue a new WAL segment. This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed. (Reported by Jens Wilke.)
- Fixed a remote timeout that occurred when a local process generated checksums (during resume or restore) but did not copy files, allowing the remote to go idle. (Reported by Jens Wilke.)
Features:
- Non-exclusive backups will automatically be used on PostgreSQL 9.6.
- Added the cmd-ssh option to allow the ssh client to be specified. (Suggested by Jens Wilke.)
- Added the log-level-stderr option to control whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior. (Suggested by Sascha Biberhofer.)
- Set application_name to "pgBackRest [command]" for database connections. (Suggested by Jens Wilke.)
- Check that archive_mode is enabled when archive-check option enabled.
