IMPORTANT NOTE: The new implementation of asynchronous archiving no longer copies WAL to a separate queue. If there is any WAL left over in the old queue after upgrading to 1.13, it will be abandoned and not pushed to the repository.
To prevent this outcome, stop archiving by setting archive_command = false. Next, drain the async queue by running pgbackrest --stanza=[stanza-name] archive-push and wait for the process to complete. Check that the queue in [spool-path]/archive/[stanza-name]/out is empty. Finally, install 1.13 and restore the original archive_command.
IMPORTANT NOTE: The stanza-create command is not longer optional and must be executed before backup or archiving can be performed on a new stanza. Pre-existing stanzas do not require stanza-create to be executed.
Bug Fixes:
- Fixed const assignment giving compiler warning in C library. (Fixed by Adrian Vondendriesch.)
- Fixed a few directory syncs that were missed for the --repo-sync option.
- Fixed an issue where a missing user/group on restore could cause an "uninitialized value" error in File->owner(). (Reported by Leonardo Avellar.)
- Fixed an issue where protocol mismatch errors did not output the expected value.
- Fixed a spurious archive-get log message that indicated an exit code of 1 was an abnormal termination.
Features:
- Improved, multi-process implementation of asynchronous archiving.
- Improved stanza-create command so that it can repair broken repositories in most cases and is robust enough to be made mandatory. (Contributed by Cynthia Shang.)
- Improved check command to run on a standby, though only basic checks are done because pg_switch_xlog() cannot be executed on a replica. (Contributed by Cynthia Shang.)
- Added archive and backup WAL ranges to the info command.
- Added warning to update pg_tablespace.spclocation when remapping tablespaces in PostgreSQL < 9.2. (Contributed by blogh.)
- Remove remote lock requirements for the archive-get, restore, info, and check commands since they are read-only operations. (Suggested by Michael Vitale.)
