In playing with a sample query from another thread I found this query is broken on the master branch:
select q1.* from (select 'a'::text) q1(c) where not exists (select * from (select 'A'::text) q2(c) where q2 = q1); I get: ERROR: subquery q2 does not have attribute 0 I checked and found it broken on 9.2 and 9.3, but working on 9.1. git bisect, says it was broken by commit 1cb108efb0e60d87e4adec38e7636b6e8efbeb57. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
