I was wondering if somebody could clear up how tablespaces are used. Let's say I have three classes of storage: - ramdisk (tmpfs) - SSD - spinning rust Furthermore, let's say I'd like to be able to tell postgresql to prefer them - in that order - until they each get full. IE, use tmpfs until it reports ENOSPC and then fall back to SSD, finally falling back to spinning rust. Is there a way to do this? -- Jon -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
