Not sure you need to use array why not simple table joins, so a table with your criteria x y z t joined to stuff to give you candidates that do match, then left join with coalesce to add the 'd'select

coalesce(a.id,b.test_id) as finalresult

left join (

Hi Hector. Hopefully this is not a stupid question...
How is that equivalent from the `NOT ARRAY ... <@ ...` though?
The inner-join-distinct above will return test_id's on any match, but you
can't know if all array values are matches. Which is different from
> Is the first array contained by the second
from the <@ operator, no?
I'm unfamiliar with these operators, so am I missing something?
Just trying to understand the logic here. Thanks, --DD
