No, there isn't. One important advantage of that is that you can do a PITR for each customer individually. If you keep all your databases in a single instance/cluster you can only do PITR for all of them. For a multi-tenant system I don't think that will be acceptable. Another advantage is, that you can have control superuser access on a per-cluster basis > But then what is the best way to handle connecting to an individual cluster > (local only for admin purposes) with psql? psql uses several environment variables for the default connection information: http://www.postgresql.org/docs/current/static/libpq-envars.html You can either create one shell script for each instance/cluster or use different OS users that have different default environment variables - that would be closer to what you have now.
