No, its not possible. Need a trigger.
I think we should support it though. If we extend the relational model
with arrays then it would be sensible if we support this aspect as
well.
Implementation would be fairly straightforward. ri_triggers currently
assumes a non-array value is being checked, but that could be changed to
IN(array). Multi-column keys with arrays sound confusing though.
What's the syntax going to look like?
