You can find the discussion about that on following link: http://www.postgresql.org/message-id/flat/CA+TgmoY4j+p7JY69ry8GpOSMMdZNYqU6dtiONPrcxaVG+SPByg@xxxxxxxxxxxxxx#CA+TgmoY4j+p7JY69ry8GpOSMMdZNYqU6dtiONPrcxaVG+SPByg@xxxxxxxxxxxxxx ----- Greetings, Samrat Revagade, NTT-DATA-OSS Center (Pune) -- View this message in context: http://postgresql.1045698.n5.nabble.com/Speed-up-Switchover-tp5765160p5765235.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
