I am trying to make some foreign keys deferrable and initially deferred. These foreign key constraints already exist so I was going to change them by updating pg_trigger and pg_constraint. However the changes do not seem to take affect. Is there something I need to do to get PostgreSQL to recognize that I have tweaked it's tables? This is the query that I used: begin work; update pg_constraint set condeferrable = true, condeferred = true where contype ='f'; update pg_trigger set tgdeferrable = true, tginitdeferred = true where tgconstrname in ( select conname from pg_constraint where contype = 'f' ); commit any help would be appreciated, Craig
