I think you need to read the code around subquery_is_pushdown_safe and qual_is_pushdown_safe some more.regards, tom lane .
In general, I'd need to go throught the pg source code which will take some time. For instance, I wanted to see which are the requirements for a patch to be accepted.
Currently, I can't provide you with a patch anyways (lack of time and knowledge). However, I can possibly give it a try in a few weeks.
If someone is working on that in the meantime, please let me know. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
