#378: Editing table properties drops all foreign keys and recreates them

When I open the properties on a table containing foreign key constraints,
and then to go the SQL tab to see what will be executed, I notice all
foreign keys are dropped and then recreated. For example when I open the
table properties for the table zulook.inv_equipment on my database, the
SQL pane reads as follow:

ALTER TABLE zulook.inv_equipment
DROP CONSTRAINT inv_equipment_company_entity_id_fkey;
ALTER TABLE zulook.inv_equipment
DROP CONSTRAINT inv_equipment_item_id_fkey;
ALTER TABLE zulook.inv_equipment
ADD CONSTRAINT inv_equipment_company_entity_id_fkey FOREIGN KEY
(company_entity_id)
REFERENCES zulook.ab_company (company_entity_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION DEFERRABLE INITIALLY
IMMEDIATE;
ALTER TABLE zulook.inv_equipment
ADD CONSTRAINT inv_equipment_item_id_fkey FOREIGN KEY (item_id)
REFERENCES zulook.inv_item (item_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION DEFERRABLE INITIALLY
IMMEDIATE;

I didn't have this behaviour problem under 1.12.x versions, I've noticed
it starting with 1.14.x versions, and now it is still present in 1.16.0. I
use pgAdmin 1.16.0 (Sep 7 2012, rev: REL-1_16_0, from binary) under
Windows XP SP3, English version but on a Canadian French OS.
