Hi, I am trying to improve delete performance on a database with several foreign keys between relations that have 100M or so rows. Until now, I have manually disabled the triggers, done the delete, and re-enabled the triggers. This works, but I have to do that when I am sure no other user will access the database... I am wondering if deferring foreign key constraints (instead of disableing them) would increase performance, compared to non deferred constraints (and compared to disableing the constraints, but I guess no in this case).
