Comment (by pimpaa):

 Hello Regina,

 The main table is not affected. I tested it quickly when it was first
 written, and everything was fine. The rules add other actions to
 INSERTS/DELETES/UPDATES. Heres a examples of a generic insert rule
 (rewritten, not using the actual function, but the desired output - check
 line 115).

 {{{
 v_sql:= CREATE OR REPLACE RULE foo_history_insert as ON INSERT TO
 public.foo
          DO (
          INSERT INTO history.foo_history VALUES(
          DEFAULT, --history_id nextval()
          DEFAULT, --date_added now()
          NULL,    --date_deleted
          quote_literal('INSERT'), --operation
          DEFAULT,
          NEW.foo_id,
          NEW.*)
          );

 }}}

 All the tables created are inherited from the main table (check line 66 in
 code).

 If the add-in is not showing off desired behavior, please let me know :D,
 and thanks for your concern.

 The debate over triggers x rules are still a question, and i'm up for
 taking any of those. Just let me know.

 Also, this was written in 8.3, and i did not checked 8.4 for 8.4
 funcionalities that could help/enhance the implementation.

 Thanks regina!
