disable foreign key checks

Hi monetdb people, I'm doing some work again on Djonet, implementing missing features. One of the features is to flush the content of a set tables e.g. remove all rows. The problem is that the order the tables are processed is important in the case of foreign key relations. They way this is implemented in other database drivers for django is to temporarily disable foreign key relations (mysql) or to TRUNCATE multiple tables in one statement (postgresql). Is there an (undocumented) way of accomplishing something similar? I prefer not to temporarily alter the table. Thanks, -- Gijs Molenaar http://www.astro.uva.nl/people/gijs-molenaar/
