At that point it's more about whether or not your server can support all the users / access going on at once. 15 or 1 db in the cluster, if you've got 200 users hitting it hard you'll need a big server. OTOH, 100 dbs in a cluster with a dozen or fewer average users is just fine. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
