Hi all, take a look at those plans:
Try changing random_page_cost from the default 4 to 2 in postgresql.conf: random_page_cost = 2 The default in postgresql is somewhat conservative. This setting indicates for postgresql how fast your disks are, the lower the faster. Could this setting be changed to 2 as default rather than 4? regards Claus
