If that is doable without much complication, then it might not be bad idea to just add additional columns to existing view (pg_settings). I think you can once evaluate the details like what additional columns (other than what pg_settings has) are required and how you want to update them. After doing so further discussion could be more meaningful. With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
