If it's a regular old inner join it doesn't matter, the query planner will figure it out. If it's a left or right join then you (hopefullly) already know the order you need to use. If it's a full outer join again it doesn't matter, the query planner will figure it out. -- To understand recursion, one must first understand recursion. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
