triggers, rules and alter table

[Sergey Karin <sergey.karin@xxxxxxxxx>]

Hi, List!

I'm using pg 8.1.0

this version allows to create triggers on INSERT, DELETE and UPDATE and
also allows to create rules on SELECT, UPDATE, INSERT and DELETE.
But I want to do some actions on ALTER TABLE ... ADD COLUMN and ALTER
TABLE ... DROP COLUMN events. How I can handle that events in 8.1.x
version?
