You'll have to provide considerably more information until we can help you. You might want to check this: https://wiki.postgresql.org/wiki/Slow_Query_Questions You have not provided the full query, just a query apparently referencing views, so that the actual query is way more complicated. Also, plain EXPLAIN is not really sufficient, we need EXPLAIN ANALYZE. regards -- Tomas Vondra http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
