WarehousePG Backup and Restore 1.33.1 release notes

Release date: May 21, 2026

WarehousePG Backup and Restore 1.33.1 includes a new feature and bug fixes.

Features

--ignore-plugin-config option for gprestore: Lets gprestore read plugin-backed backup files directly, without requiring --plugin-config or a hand-edited config YAML.

Fixed a hang when backing up with --single-data-file. gpbackup no longer assumes that tables to back up have sorted object IDs (OIDs) in this mode. Previously, if an extension config table had a lower OID than user tables, the backup helper crashed and hung the backup procedure indefinitely.
Fixed a hang in TerminateHangingCopySessions on WarehousePG 6. After the pgx/v5 upgrade, terminating a hanging COPY session on WarehousePG 6 caused the driver to silently retry the COPY on a new connection, creating an orphaned session that deadlocked cleanup. gpbackup now cancels the backend instead of terminating it, avoiding the retry.
