Обсуждение: restrict modification of column values in BR triggers
Hi,
is there any way to prevent role from modifing values of some columns of NEW row in before row triggers? I revoked insert privilege from these columns to ensure that only default value can be inserted, but it is still posible to modify values being inserted using before row triggers. I can't revoke trigger privilege on that table, because this role must be able to create triggers on this table.
Thank you.
Best regards

If you give someone trigger privileges on your table, that's pretty much game over. The trigger functions they create will run as you. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
