I think jdbc always uses cursor, which can be problematic with default configuration, because postgres will try to generate plans that returns fast the first rows but not all the rows . Can you try to configure cursor_tuple_fraction to 1 and see if that fixes your issue? -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
