By the way, rather than dropping the foreign key then recreating it, you could always do this: ALTER TABLE tablename DISABLE TRIGGER ALL; Then it would ignore the foreign key trigger and you could put in mischievous values... but remember to enable it again (replace DISABLE with ENABLE). You'll have to be a superuser to do it though. -- Thom Brown Twitter: @darkixion IRC (freenode): dark_ixion Registered Linux user: #516935 EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
