Here are two (not necessarily mutually exclusive) options for you:
1) use triggers/rules on the master table and do all your inserts
directed to it and have the trigger/rule do the right thing
2) write your insert/update/delete statements to use the correct
inherited table directly, and write a trigger on the master that
denies any inserts.
Did you read the documentation on partitions? It covers this.
