Just as a question to Tom and team, I saw a post a bit ago, about plans for 8.4, and Tom said it is very likely that 8.4 will rewrite subselects into left joins, is it still in plans?
I mean query like: select id from foo where id not in ( select id from bar); into: select f.id from foo f left join bar b on f.id=b.id where b.id is null; the latter is most often much much faster on 8.1-8.3; thanks. -- GJ -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
