Disabling referential integrity

[Sharon Cowling]

Hi, my problem is this:

I have a table called faps_key the unique identifier being key_code:

taupo=# \d faps_key
Table "faps_key"
Column | Type | Modifiers
-----------------+-----------------------+-----------
key_code | character varying(6) | not null
date_key_issued | date |
date_key_due | date |
key_issued_by | character varying(12) |
description | character varying(20) |
comments | character varying(30) |
permit_id | integer |
status | character varying(10) |
Primary key: faps_key_key_code_pk
Triggers: RI_ConstraintTrigger_243657,
RI_ConstraintTrigger_243665,
RI_ConstraintTrigger_243667

Problem is the users now want the old key_codes deleted, and new ones entered, some of which are the same as the old ones. So I need to disable the referential integrity constraints in order to delete the old codes and input the new ones. I've had a look through the archives and at the below link, however i'm having trouble.

Associated tables are:

\d faps_permit
Table "faps_permit"
Column | Type | Modifiers
-------------------+------------------------+-----------
permit_id | integer | not null
person_id | integer | not null
date_from | date | not null
date_to | date | not null
location | character varying(30) | not null
purpose | character varying(30) | not null
subpurpose | character varying(30) | not null
vehicle_rego | character varying(6) |
vehicle_type | character varying(30) |
dogs | character varying(3) |
permit_conditions | character varying(300) |
other_info | character varying(300) |
issued_by | character varying(12) | not null
issue_date | date |
permit_printed | integer |
firearms_licence | character varying(20) |
drivers_licence | character varying(10) |
cancel_permit | character varying(10) |
Primary key: faps_permit_permit_id_pk
Triggers: RI_ConstraintTrigger_243659,
RI_ConstraintTrigger_243661

\d archive_faps_key
Table "archive_faps_key"
Column | Type | Modifiers
-----------------+-----------------------+-----------
key_code | character varying(6) | not null
permit_id | integer | not null
date_key_issued | date |
date_returned | date |
date_key_due | date |
status | character varying(10) |
key_issued_by | character varying(12) |
Primary key: archivefapskey_keycode_permit_i
Triggers: RI_ConstraintTrigger_243663

I checked out the following link, and followed the instructions

http://techdocs.postgresql.org/techd...lintegrity.php

but i still can't delete rows.

As you can see from below all tgenabled fields are set to 'f'. but further below when I try to delete it still fails.
taupo=> select * from pg_trigger;

(7 rows)

taupo=> delete from faps_key where substring(key_code from 1 for 1) = 'B';
ERROR: archivefapskey_keycode_fk referential integrity violation - key in faps_key still referenced from archive_faps_key

Any ideas about how best to go about solving my problem?

Best Regards,

Sharon.
