WarehousePG Disaster Recovery 1.1.0 release notes

Released: 28 Sep 2026

WarehousePG Disaster Recovery 1.1.0 adds ppc64le packages and fixes for backing up and restoring clusters that use tablespaces.

Adds ppc64le packages for RHEL-compatible 8 and 9. ppc64le packages work with WarehousePG 7 only.
whpg-dr list-cluster now shows the WHPG_DR_HOME path for each cluster, even when no cluster is configured. It also lists clusters that have only a restore configuration, such as restore-only recovery hosts.

Fixed restores that left every tablespace unreachable. After a restore, whpg-dr now points each pg_tblspc symbolic link at the correct per-segment tablespace directory before WAL replay. For restores started with an earlier version, whpg-dr restore --resume-failed restores segments with broken links again, and whpg-dr restore --delta and whpg-dr promote refuse to run until the links are fixed.
Fixed POSIX backups that silently skipped tablespace data. Backups now capture each segment's tablespace directory and fail if the copy doesn't complete, for example when a tablespace file system isn't mounted.
Fixed concurrent segment restores from POSIX storage on the same host deleting each other's tablespace files, and a race when parallel restores shared a tablespace location.
Cancelling a backup or restore now reliably terminates local and remote Barman processes before whpg-dr releases state files and cluster locks.
Fixed deleted backup metadata being recreated by a Barman process that was still running.
Fixed remote shell commands that contain single quotes.
