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!
Thanks,
Brad
