I've got a customer that discovered something odd...
SELECT f1 FROM v1 WHERE f2 not in (SELECT bad FROM v2 WHERE f3 = 1);
does not error, even though bad doesn't exist, but
SELECT bad FROM v2 WHERE f3 = 1;
gives
ERROR: column "bad" does not exist
Is that expected?
This is on 9.4.8, and both v1 and v2 are views. The only "odd" thing
that I see is that v1 is a UNION ALL and v2 is a UNION. I don't think
there's any tables in common between the two views.
