I referred chapter 14.3 of postgres document version 9.0. explicit joins help the planner in planninng & thus improve performance. On what relations are explicit joins to be added?? I am getting data from 10 tables in a view. I don't know on which pair of tables I have to add explicit joins to improve performance. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Explicit-joins-tp4372000p4372000.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
