here's a small patch, not sure where to submit it.

This version should prove faster as it halves the number of writes,
however it still does a lookup.

this code replaces similar code in 
etc/raddb/sql/postgresql/update_radacct_group_trigger.sql 

----

CREATE OR REPLACE FUNCTION upd_radgroups() RETURNS trigger AS'
BEGIN
	IF NEW.groupname IS NULL THEN 
		NEW.groupname = groupname
			FROM radusergroup 
			WHERE calledstationid = NEW.calledstationid
				AND username = NEW.username;
	END IF;
	RETURN NEW;
END
'LANGUAGE plpgsql;

DROP TRIGGER upd_radgroups ON radacct;

CREATE TRIGGER upd_radgroups BEFORE INSERT ON radacct
    FOR EACH ROW EXECUTE PROCEDURE upd_radgroups();
