yeah! i was thinking on doing that but still have no time... and
frankly you're the best man for the job ;)

one thing i was thinking of is to use triggers instead of rules just
as our current docs recommends
http://www.postgresql.org/docs/8.3/static/ddl-partitioning.html

with the benefit that a trigger can check if the child table exists
for the range being inserted and if not it can create it first...
haven't looked at the code in the detail but seems that your patch is
still missing the "create rule" part so we are in time to change
that... no?

Yes triggers should be used instead of rules. Automatic generation of rules/triggers would be kind of hard and needs some looking into. Also there are issues like checking mutual exclusivity of the partition clauses specified too (I have been maintaining that the onus of ensuring sane partition ranges/clauses should rest with the users atleast initially..).

I will take a stab at this again whenever I get some free cycles.
