Here's the problem: test=> CREATE TABLE a ( refb OID, at INT2 ); test=> CREATE TABLE b ( refa OID, bt INT2 ); test=> CREATE RULE ar AS ON UPDATE TO a.at test-> DO UPDATE b SET b.bt = NEW.at test-> WHERE refa = OLD.oid; ERROR: attribute level rules currently not supported What am I doing wrong? I've read and re-read chapter 8 - rules from the postgresql programmer's guide, but I can't see why this rule doesn't work. Any suggestions would be appreciated. Marc ************
