Thank you very much for the response. > Can you do online purging? > For example, get a list of the main table's primary keys to be deleted, and > then nibble away at them all day: in one transaction delete all the records > for one logically related set of records. Do that N million times, and > you've purged the data without impacting production. So, with this approach, is the advantage like, manual vacuuming worry may be set aside, because auto-vacuuming would dealwith the dead rows? This is because the deletion step is executed record by record in main table, with its connectedrecord(s) delete executions in rest of tables? Due to the infra capability that is there in this instance, the impactcould be almost none!!?? Thank you...
