RE: Views and default values

I think that a coalesce might work here, something like:

create rule v_foo_ins as on insert to v_foo do instead
insert into foo (explication, silly) values (
NEW.explication,
COALESCE(NEW.silly, 'DEFAULT_VALUE'));

Obviously you replace the DEFAULT_VALUE with whatever you want your default
to be.

Cheers...
