This may be a confusion on the point of equivalence; clearly the features work differently. I'm not aware of any rule that can't be rewritten as a trigger or a view. Please can anyone show me some examples of those? Assuming examples exist, do we think that is wide enough to be considered a useful feature, given the other downsides of rules such as not abiding by COPY - which causes data corruption for those who thought rules would always be obeyed. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
