This option controls if toast tables associated with a relation are vacuumed or not when running a manual VACUUM. It was already possible to trigger a manual VACUUM on a toast relation without processing its main relation, but a manual vacuum on a main relation always forced a vacuum on its toast table. This is useful in scenarios where the level of bloat or transaction age of the main and toast relations differs a lot. This option is an extension of the existing VACOPT_SKIPTOAST that was used by autovacuum to control if toast relations should be skipped or not. This internal flag is renamed to VACOPT_PROCESS_TOAST for consistency with the new option. A new option switch, called --no-process-toast, is added to vacuumdb.
