So, with this approach, is the advantage like, manual vacuuming worry may be set aside, because auto-vacuuming would deal with the dead rows? This is because the deletion step is executed record by record in main table, with its connected record(s) delete executions in rest of tables? Due to the infra capability that is there in this instance, the impact could be almost none!!??
Thank you...
