9) as remarked up a different thread, more than one clause could be pushed down a subquery. The current patch only considers alternative paths that have at most one clause pushed down. Is this because of the call site of best_inner_subqueryscan, i.e. under one join rel? Would it be an idea to consider, for each subquery, only a single alternative plan that tries to have all suitable clauses pushed down?
Ehm, please forget this remark, I've mistaken join rel for base rel. -- Yeb -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
