PostgreSQL's rules and nextval()/serial problem (very PostgreSQL-specific)

Question

When I use a rewrite rule that splits an insert into one table into inserts to two other tables where one of the inserted values has as default nextval(\'some_sequence\') with t

Answer 1

Rules will do that for you - they rewrite the query before it's executed.

As long as you have an actual table for the base (Children1), I think you'll be able to accomplish the same thing with a TRIGGER instead of a RULE.
