Last night I just upgraded to a nightly snapshot of 7.4 and noticed an
error on queries that had previously worked (in version 7.3.x and
previous 7.4's snapshots up to about a month old).
I have a view that I can distill into a base case of:
CREATE VIEW testing_v AS SELECT table_a.* FROM table_a WHERE (table_a.some_id IN ( SELECT DISTINCT
table_b.some_id FROM table_b ));
When I do :
select * from testing_v;
I get:
JOIN qualification may not refer to other relations
I have found that if I remove the distinct on the sub-query, it behaves
as expected.
Yes, I know the distinct is probably useless but we are in the process
of porting it to postgres and have lots of cleanup left.
We are migrating from a commercial database (and paid good money) and
found postgres to be a joy (substantially fast, less gotchas, better at
embeding business logic at db level).
Thank you very much. I appreciate all the effort that has put into such
a great product.
