…e restore A repeat in-place PostgreSQL RestoreJob into an already-restored target silently no-opped: the destructive purge was skipped because the live Cluster still carried spec.bootstrap.recovery left over from the previous restore, and the re-purge guard mistook that for a freshly-recovered Cluster produced by this restore's own purge. The job then reported Succeeded while the PVC, disk, and data were never touched. Tell the two apart by the Cluster's creationTimestamp relative to the RestoreJob's StartedAt: only a recovery Cluster created at/after StartedAt is treated as this restore's own and skipped; one that predates StartedAt is leftover from an earlier completed restore and is purged so the restore re-bootstraps from the backup. Signed-off-by: Ivan Okhotnikov <[email protected]> (cherry picked from commit cf1b6ba) (cherry picked from commit c85c9f3) (cherry picked from commit 507a48762292665343195da99913d64d4b256906)
…onservative freshness tie Address review feedback on the repeat in-place restore fix: - Make the freshness discriminator strict (creationTimestamp > StartedAt) so an exact tie resolves to "not fresh" and the caller purges, matching the function's stated conservative default; a fresh Cluster is always created well after StartedAt so this never misclassifies the status-write-race path. - Document why a wall-clock timestamp comparison was chosen over recording the purged Cluster's UID on the TargetPurged condition (the UID approach leans on the same status write the race path assumes can fail). - Add a reconcile-level regression test that drives reconcileCNPGRestore end to end with a fake client: a stale leftover recovery Cluster from a prior restore is purged, and a Cluster this restore just re-created is not re-purged. This covers the actual call site where #3311 lived, not just the pure helpers. Signed-off-by: Ivan Okhotnikov <[email protected]> (cherry picked from commit a8494d8) (cherry picked from commit 0fdf3b5) (cherry picked from commit 2d6083ccb6f418a35ba1ae058b3a91f7edcc89fd)
