CVE-2026-50738: Postgres Xact Callback Missing Abortcve-2026-50738-postgres-xact-callback-missing-abort

PostgreSQL transaction callback handles commit events without handling XACT_EVENT_ABORT. Transaction-scoped memory is reset on abort, which can cause use-after-free or dangling pointer dereferences in subsequent transactions.
