deleted i get the following error Error insert or update on table5
violates foreign key constraint "table4". They are all link with a
cascade delete.
As Stephen said, it's difficult to help without more details about the triggers and the structure of your transaction. However, if you expect that the constraints are consistent at the end of the transaction, perhaps the problem is merely the order in which constraints are checked. See
http://www.postgresql.org/docs/8.1/interactive/sql-set-constraints.html and consider something like SET CONSTRAINTS ALL DEFERRED .
