Hey Scott, that's ingenious, only thing is that I use NOT NULL for many data columns too, where the value may or may not be passed in. Will try with a COALESCE and will post back here.

Thx again!

Hi,

I use views extensively to implement security on tables. This requires each table to have a view. All updates, inserts and deletes take place through the view. The view has rules for each of these operations defining security for that table. Under other conditions, the view also removes complex views of the underlying data from the application layer by supplying a view where the rules for update, insert and delete implement business logic.

The problem is that rules on a view mean that the default values for NOT NULL columns (used extensively) no longer trigger!

E.g.

Table A had column "updated_time" which is not null default now().
Inserting into the view on table A where "updated_time" has not been supplied will not fill in "now()". It will attempt to put in a null value and hence the insert will fail in the insert rule on that view.


Is there any way to tell PG to implement the triggers on the underlying table? It will make it extremely difficult to implement this schema if I have to try to put in null field handling... and it really should be PG doing this not me! No doubt if this is a bug, it will be fixed in 8.x!



Try changing the udpate triggers you're creating to pass in DEFAULT (similar to NULL in the way it's NOT quoted, etc...) in the update / insert query to the lower level and see if that fixes things.
