 * OPTIONAL Postgresql trigger for FreeRADIUS
 *
 * This trigger updates fills in the groupname field (which doesnt come in Accounting packets)
 * by querying the radusergroup table.
 * This makes it easier to do group summary reports, however note that it does add some extra
 * database load to 50% of your SQL accounting queries. If you dont care about group summary
 * reports then you dont need to install this.
