Your hardware has a lot to do with this though. Applying changes to a machine with plenty of memory, fast CPUs, and a big rockin RAID-10 array will of course be much faster than doing the same thing on a laptop. If you make "base" sets every night at midnight with snapshots, then it shouldn't take too long. Is this gonna be a regular thing, or is this more of an occasional occurance when things in the game go horribly wrong? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
