The decoding worker records the relfilenumber of the TOAST table when it starts, and skips changes stored under any other one, but the TOAST table was not locked until the data copy began. If VACUUM FULL rewrote it while the worker was starting, concurrent updates of TOASTed columns were silently lost. Fix by locking the TOAST table in cluster_rel() in the concurrent case, before the worker starts.
