When you have a full set of constraint, then you don't need to validate input. Just you will execute statement. When execution is correct, then all is ok, when not, then you have to recheck message, err code, ... and you have to verify, so some exception is expected or not. This is programming based on exceptions. Some better structured information helps. And what's more - this should be in conformity with ANSI SQL. regards Pavel Stehule -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
