Use psql to directly output query results to a file instead of using COPY
to output structured output in a format you don't want.

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
--a.id,b.test_id,
coalesce(a.id,b.test_id) as finalresult
from test a
left join (

return all “not containing the specified array”, including entries in master
table not being referenced.
I have the following schema:
drop table if exists stuff;
drop table if exists test;
CREATE TABLE test(
id
