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.
