You might want to go and read the documentation: http://www.postgresql.org/docs/current/interactive/runtime-config-resource.html But at any rate, the large work_mem was producing a very strange plan. It may help to see what the system does without that setting. But changing shared_buffers will not change the plan, so let's not worry about that right now. ...Robert -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
