Yes. And the same is true for stored procedures when we'll
get them.

Agreed. I didn't object but of course I more like general solution
- a way to invalidate stored rules/procedures/etc and re-compilate
them when need.

BTW, what's your plan for RI constraints, Jan?
Did you see my letter about statement level triggers?
If I'll get WAL implemented then it could be used for RI.
In any case I believe that statement level triggers
are very nice thing and they are better for RI than
rules.
